Abstract:
The control of quenching process has been investigated in this study by developing a quench system design to simulate the quenching process and measure the time – temperature history inside the sample during the cooling stage. The main purpose of this quench system is to evaluate the quench power of different quenchant at different conditions (type, temperature and agitation).A stainless steel sample was used with a suitable measurement as a probe in designing this quench system.The performance of two of quenchants (water and brine) with different conditions was investigated, and the designed probe was used to illustrate the effect of quenching parameters (quenchant type, temperature and its agitation) on cooling curves and cooling rate.The quenching system has proven its ability to work effectively and the results showed that heat transfer properties were significantly affected by quenchant parameters.

Abstract:
To control the process of film boiling during quenching in oils, quench oil makers as a rule manipulate physical properties such as a surface tension and viscosity. However, there is much experimental data showing that special additives can eliminate film boiling in oils without changing their physical properties and which is counterintuitive. Authors explain such phenomenon by showing that the addition of a special additive, for example PIB (polyisobutylene polymer), will create an insulating layer on the surface of steel parts during quenching in oils that will eliminate film boiling without affecting physical properties of the oil. Insulating layer decreases initial heat flux density which becomes less than critical one and of the oil will not begin film boiling during quenching with the PIB additive. Authors believe that such approach will allow engineers to solve effectively the problem of part distortion after quenching. The new oil quenchant containing special additive PIB is patented in Ukraine and is manufactured by Barkor Ltd for needs of the heat treating industry.

Abstract:
Si-Mn spring steel (JIS SUP 9) is primarily employed in the construction of coil springs, particularly those used in soil cultivators deployed in harsh environments. This is due to its specific properties, which allow it to resist permanent deformation, and also provide rapid and effective vibration relief. Si-Mn spring steel (JIS SUP 9) for use in such projects is normally subjected to oil quenching and heat treatment, in order to strengthen its resistance to both impact and fatigue. Unfortunately, oil quenching is associated with environmental issues, most notably pollution and the contamination of wastewater with oil. Therefore, the objective of this study was to describe an alternative aqua quenching for use with this heat treatment. However, aqua quenching has traditionally conferred a lower tensile laod than does oil quenching. This problem of lesser tensile load was solved by properly controlling the density and temperature of the aqua quenching liquid, as well as careful mixing. As a result, it has proven possible to achieve results with aqua similar to those conferred by oil quenching, with regard to chemical components, tensile load, and surface hardness. The tensile load results achieved by oil quenching were 13,145 Pa and 17,177 Pa, and the tensile loads achieved with aqua quenching were 15,392 Pa, 16,804 Pa, 17,923 Pa, and 18,668 Pa. Therefore, the results of our experiments demonstrated the appropriacy and efficacy of this aqua quenching technique as a component of heat treatment for Si-Mn spring steel (JIS SUP 9).

Abstract:
Influence of sub-temperature quenching temperature on the tensile strength, hardness and toughness of 35CrMo steel was studied. The microstructure characteristics of this steel after sub-temperature quenching were analyzed. The results showed in the range of 780~810°C the strength and hardness of the 35CrMo steel sub-temperature quenched increased with quenching temperature increasing, reached the highest strength and hardness at 800°C quenching and then began to decrease, while its elongation decreased with the quenching temperature increasing. The duplex microstructure of martensite and ferrite was obtained by sub-temperature quenching of 35CrMo steel. With the quenching temperature increasing, the ferrite content decreased and the distribution of ferrite morphology was changed. A small amount of strip ferrite existed in lath martensite lamellar when quenching temperature was 800°C and the impact toughness of 35CrMo steel was better than that of conventional samples 850°C completely quenched.

Abstract:
The fluorescence quenching studies of 6-bromo-3-azidoacetyl coumarin (6BAAC) by aniline in four different solvents, namely acetonitrile, benzene, dioxane, and toluene, were carried out at room temperature to understand quenching mechanisms. The Stern–Volmer plots have been found to be nonlinear with a positive deviation for all the solvents studied. To interpret these results we have invoked the ground state complex formation and sphere of action static quenching models. Using these models various quenching rate parameters have been determined. The magnitudes of these parameters suggest that the sphere of action static quenching model agrees well with the experimental results. Hence the positive deviation is attributed to the static and dynamic quenching. Further, with the use of the finite sink approximation model, it was possible to check these bimolecular reactions as diffusion-limited and to estimate independently distance parameter R′ and mutual diffusion coefficient D. Finally an effort has been made to correlate the values of R′ and D with the values of the encounter distance R and the mutual coefficient D determined using Edward’s empirical relation and the Stokes–Einstein relation.

O processo de Têmpera e Partição (T&P) possibilita a produção de aços com frações controladas de austenita retida, a partir do enriquecimento da austenita pela partição de carbono da martensita sem a precipitação de carbonetos. A austenita retida proporciona o efeito TRIP (plasticidade induzida por transformação), que confere ao material uma deformação uniforme e uma melhor absorção de energia durante o impacto. Os aços produzidos por este processo atendem principalmente às necessidades da indústria automobilística, que busca aços com melhores propriedades para a diminuição de peso e aumento da segurança dos automóveis. Nesta dissertação, ligas de aço com diferentes composições e tamanhos de grão foram produzidos pelo processo de Têmpera e Partição e a fração de austenita retida foi medida por difração de raios-X. As ligas também foram caracterizadas por nanoindentação, microscopia ótica e microscopia eletrônica de varredura. As amostras estudadas foram produzidas com uma austenitização completa a 930°C, realizada para promover um aumento no tamanho de grão, e os resultados foram comparados com amostras estudadas anteriormente com temperatura de austenitização de 890°C. Os resultados obtidos indicaram um aumento da fração de austenita retida com o aumento do grão austenítico original. Estes resultados foram interpretados com base no modelo teórico desenvolvido para o processo T&P.
The Quenching and Partitioning (Q&P) process allows the production of steels with controlled fractions of retained austenite from the enrichment of the austenite by carbon partitioning from the martensite without carbide precipitation. The retained austenite is responsible for the TRIP effect (transformation induced plasticity), which enhances the material behavior providing a uniform strain and a better energy absorption during impact. Steels produced by this process match the requirements of the automotive industry, which looks for weight reduction and safety improvements in cars. In the present dissertation, steels with different compositions and grain sizes were produced by the Quenching and Partition process and their retained austenite fraction was measured by x-ray diffraction. The steels were also characterized by nanoindentation, optical microscopy and scanning electron microscopy. The specimens studied were produced by a complete austenitization at 930°C, to promote an increase in the austenitic grain size, and the results were compared with previously studied specimens produced by a complete austenitization at 890°C. The experimental results indicate an increase of austenite fraction with an increase in grain size of the original austenite. These results were analyzed based on the theoretical model develop for the Q&P process.

Abstract:
In the present study, the influence of the quenching temperature and partitioning conditions (temperature and time) have been investigated on a 0.6%C-1.2%Mn-1.6%Si-1.75%Cr alloy. Maps of hardness, impact toughness and amount of retained austenite have been developed for three quenching temperatures as a function of partitioning temperature and partitioning time. Results demonstrate that, in this material, the carbon depletion of the martensite and the stabilization of austenite can be achieved significantly faster at high partitioning temperatures, promoting higher retained austenite fractions, lower hardness, and maximizing the energy absorbed in a Charpy V‑Notch test. In addition, the effect of the partitioning time was also analysed, presenting different behaviour at high and low partitioning temperatures. Whereas an increment of time at high partitioning temperatures (>400 ºC) leads to an austenite consumption, at low partitioning temperatures it is effective to retain a higher amount of austenite.  Furthermore, tensile properties are shown to be better than in conventional alloys utilized in industry. Whilst, for example, the AISI 52100 alloy achieves 2 GPa of tensile strength and 1‑2% of fracture deformation, in the present study the notable combination of 2.5 GPa of tensile strength and 5.7 % of fracture deformation was achieved in samples quenched until room temperature. Untempered martensite transformed during final cooling in samples quenched until higher temperatures was shown to be detrimental for tensile properties. A comparison between the Q&P process and the austempering process on this alloy has been carried out. Results reveal that the quenching and partitioning heat treatment is presented as a promising alternative to reach higher hardness (>700 HV) and similar specific wear rates in dry conditions performing a shorter heat treatment.    Finally, a complementary study about the effect of micro-segregation on the Q&P process and an optimization method to minimize the inhomogeneity of the structure by a correct selection of the quenching temperature were established.

Abstract:
The Quenching and Partitioning (Q&P) heat treatment has been proposed in the early 2000s to produce cold-rolled sheets combining high-strength and formability for the automotive market. Q&P consists, first, of an interrupted quench between the martensite-start temperature (Ms) and the martensite-finish temperature (Mf) from intercritical annealing or full austenitization in order to form controlled fractions of martensite. This is followed by a partitioning step in order to stabilize the untransformed austenite through carbon enrichment. In order to maximize the carbon transfer from martensite to austenite, the use of specific alloying elements and the design of appropriate Q&P parameters are required to eliminate or minimize competing phenomena such as carbide formation and austenite decomposition. The final quenched and partitioned microstructure, using full austenitization, ideally consists of carbon-depleted lath martensite and significant fractions of retained austenite providing an improved combination of strength and ductility. Hence, the transformation of retained austenite upon straining at room temperature (TRIP effect) provides supplementary work-hardening and eventually improves the ductility. In the present work, Quenching and Partitioning (Q & P) heat treatments were carried out in a quench dilatometeron a 0.2 wt% carbon steel. The microstructure evolution of the Q & P steels was characterized usingdilatometry, SEM, EBSD and XRD. The martensitic transformation profile was analyzed in order to estimate thefraction of martensite formed at a given temperature below the martensite start temperature Ms. Q & P wasshown to be an effective way to stabilize retained austenite at room temperature. However, the measuredaustenite fractions after Q & P treatments showed significant differences when compared to the calculated valuesconsidering ideal partitioning conditions. Indeed, the measured austenite fractions were found to be less sensitiveto the quench temperature and were never larger than the ideal predicted maximum fraction. Competitivereactions such as austenite decomposition into bainite and carbide precipitation were found to occur in thepresent work.Furthermore, a broad range of mechanical properties was obtained when varying the quenching temperaturesand partitioning times. The direct contributions between Q & P microstructural constituents -such as retainedaustenite as well as tempered/fresh martensite- and resulting mechanical properties were scrutinized. This wascritically discussed and compared to quenching and austempering (QAT) which is a more conventional processingroute of stabilizing retained austenite at room temperature. Finally, Q & P steels were shown to exhibit aninteresting balance between strength and ductility. The achievement of this interesting combination of mechanicalproperties was reached for much shorter processing times compared to QAT steels.

Abstract:
Abstract The effect of austenite pancaking in the non-recrystallisation regime on microstructure and mechanical properties, especially bendability, was investigated in direct-quenched ultrahigh-strength strip steels with martensitic-bainitic microstructures. Lowering the finishing rolling temperature (FRT) increased total reduction in the non-recrystallisation region (R tot). Niobium microalloying increased Rtot while variations in C, Mn and Mo did not affect Rtot to the same extent as Nb. A decrease in the FRT increased the incidence of softer microstructures such as ferrite and granular bainite in the subsurface layers. The microstructures at the centreline were comprised of auto-tempered martensite with some bainite. An increase in Rtot strengthens the intensities of the ~{554}<225>α and ~{112}<110>α texture components at the centreline and the components ~{112}<111>α and ~{110}<112>α - {110}<111>α at the strip subsurface. Bendability is poorer with the bend axis perpendicular rather than parallel to the rolling direction (RD) and is further impaired with increasing hardness below the sheet surface. An intense ~{112}<111>α shear texture combined with upper bainite containing MA islands in the subsurface region is shown to be detrimental to bendability when the bend axis is perpendicular to the RD. This anisotropy of bendability can be explained by the appearance of geometric softening in grain clusters belonging to this texture component when the bend axis is perpendicular to the RD. Shear localisation is prevented, however, by the presence of a sufficiently thick subsurface microstructure having adequate work hardening capacity, i.e., ferrite + granular bainite rather than ferrite + upper bainite. The strain required to initiate strain localisation can be increased and good bendability thereby achieved—even in the presence of detrimental texture components—by ensuring the presence of a sufficiently soft subsurface layer extending to a depth of approximately 5% of the total sheet thickness. The above beneficial microstructures can be obtained and good bendability ensured in direct-quenched strip steel with a yield stress above 900 MPa together with good impact toughness, provided a suitable combination of chemical composition and processing parameters is selected and sufficient attention is paid to steelmaking operations to obtain a proper inclusion structure
Tiivistelmä Austeniitin muokkauksen vaikutusta mikrorakenteeseen ja mekaanisiin ominaisuuksiin, erityisesti särmättävyyteen, tutkittiin suorasammutetuilla martensiittis-bainiittisilla suurlujuusnauhateräksillä. Kuumavalssauksen lopetuslämpötilan lasku kasvatti austeniitin kokonaisreduktiota ei-rekristallisaatioalueella. Mikroseostus niobilla kasvatti myös kokonaisreduktiota, kun taasen muutokset C-, Mn- ja Mo -pitoisuuksissa eivät vaikuttaneet yhtä voimakkaasti. Valssauksen lopetuslämpötilan lasku kasvatti pehmeämpien mikrorakenteiden, kuten ferriitin ja granulaarisen bainiitin, määrää nauhan pintakerroksessa. Terästen keskilinjan mikrorakenteet koostuivat pääasiassa itsepäässeestä martensiitista sekä pienestä määrästä bainiittia. Kokonaisreduktion kasvu voimisti ~{554}<225>α - ja ~{112}<110>α -tekstuurikomponentteja keskilinjalla sekä ~{112}<111>α- ja ~{110}<112>α - {110}<111>α -komponentteja nauhan pintakerroksessa. Särmättävyys oli huonompi särmän ollessa poikittain valssaussuuntaan nähden kuin pitkittäin. Pintakerroksen kovuuden kasvu heikensi särmättävyyttä. Pintakerroksen voimakas ~{112}<111>α -leikkaustekstuuri, yläbainiitin ja MA-saarekkeiden läsnä ollessa, osoittautui haitalliseksi särmän ollessa poikittain valssaussuuntaan nähden. Särmättävyyden anisotrooppisuus voidaan selittää geometrisella pehmenemisellä rakeissa, joissa kyseinen tekstuurikomponentti on voimakas. Leikkausmyötymän paikallistuminen estyy, kun pinnassa on riittävän paksu hyvän muokkauslujittumiskyvyn omaava kerros, mikä sisältää esim. ferriittiä ja granulaarista bainiittia, mutta ei ferriittiä ja yläbainiittia. Särmättävyys osoittautui pysyvän hyvänä huolimatta haitallisesta tekstuurikomponentista, kun pehmeä pintakerros ulottui noin 5 % syvyydelle levyn paksuudesta. Edellä mainitut mikrorakenteet ja hyvä särmättävyys voidaan saavuttaa suorasammutetuilla yli 900 MPa myötölujuuden nauhateräksillä yhdessä hyvän iskusitkeyden kanssa, kunhan valitaan sopiva kemiallisen koostumuksen ja valmistusparametrien yhdistelmä sekä kiinnitetään huomiota teräksen sulkeumapuhtauteen

Abstract:
This report presents an experimental result on quenching which affected by the Radiation Induced Surface Activation. Increasing of quenching velocity requires that the cooling liquid can contact the heated surface, or a high wettability of the surface when quenching initiates. From this point of view, an experimental study to investigate the relationship between surface wettability and quenching was performed by use of an oxide semiconductor-coated material after γ-ray irradiation. The results showed that highly surface wettability or highly hydrophilic condition of a simulated fuel rod made of SUS was achieved, and the quenching velocities were increased up to 15% after 300 kGy 60Co γ-ray irradiation.

Abstract:
The transient pool boiling heat transfer of zircaloy and stainless steel rodlets was investigated using a quenching method. The influences of quenchant temperature, test specimen size, and material property were examined. The groove-structured surface was also prepared and tested, which could be a valuable attempt to study the effect of a machined surface structure of a vertical rodlet on the rapid cooling heat transfer performance. A test specimen with a small volume-to-heat transfer surface area and small heat capacity showed a shorter quenching time. In the low quenchant temperature condition, a stable film boiling regime was likely to be hardly observed. The grooved surface appeared to have a shorter quenching duration, which could be due to its small volume-to-area ratio. In addition, the groove-structured portion seemed to help the liquid make contact with the heated wall earlier than the plain portion. Based on this work, it was found that the quenching duration and the position of vapor film rupture can be controlled by the surface structure.

Abstract:
A high-temperature stainless-steel sphere was immersed into various salt solutions to test film boiling behavior at vapor film collapse. The film boiling behavior around the sphere was observed with a high-speed digital-video camera. Because salt additives enhanced condensation heat transfer, the observed vapor film was thinner. Surface temperature of the sphere was measured. Salt additives increased the quenching (vapor film collapse) temperature, because frequency of direct contact between sphere surface and coolant increased. Quenching temperature rises with increased salt concentration. The quenching temperature, however, approaches a constant value when the slat concentration is close to its saturation concentration. The quenching temperature is well correlated with ion molar concentration, which is a number density of ions, regardless of the type of hydrated salts.

Abstract:
Abstract An experimental study of the effect of liquid subcooling on the minimum film boiling temperature during quenching of a simulated nuclear fuel rod was performed under carefully controlled laboratory conditions. The rod was designed and fabricated with a proper combination of cladding and filler materials and was instrumented with embedded thermocouples distributed at various axial and radial locations. Quenching of the rods was done using distilled water with various degrees of subcooling as the working fluid. It was found that the rate of quenching depends strongly on the liquid subcooling. Multiple maxima were observed between film and nucleate boiling in the boiling curve for high subcoolings. Increasing subcooling had the effect of moving the entire boiling curve up and to the right, resulting in a considerably high minimum film boiling temperature. The strong effect of liquid subcooling on the quenching of a fuel rod should be properly accounted for in the study of reflood heat transfer in a nuclear reactor following a design-based accident.
