Abstract:

The cyclic elastic-plastic behavior of SUS 304 stainless steel was investigated experimentally under various temperatures and temperature-changing conditions. The specimens were cyclically loaded between fixed axial strain limits at constant temperatures in the range from room temperature to 600°C. The effects of the cyclic strain amplitude on the saturation property of cyclic hardening were obtained at various temperatures. The effects of temperature variations on the cyclic hardening were examined under the temperature conditions of changing between two different temperatures. From these exp

Abstract:

Thermo-mechanical cyclic experiments on 304 stainless steel were performed at several temperature ranges which had maximum temperatures ranging from 350°C to 1000°C and a minimum temperature of 150 °C. Related isothermal cyclic experiments were also performed. Temperature-history dependent cyclic hardening significantly occurred under thermo-mechanical cyclic loading with maximum temperatures around 600°C, whereas almost no cyclic hardening was observed when the maximum temperature was 1000°C. The observed thermo-mechanical cyclic plastic behavior in the saturated state of cyclic hardening was

Abstract:

Die steels with regulated austenitic transformation during exploitation (RATE steels) are a new class of tungsten-free steels for hot forming at operating temperatures up to 750 – 800 °C. High durability of the pressing tool and its long service life are ensured by the ability of these steels to preservation of hot work hardening. This circumstance distinguishes RATE steels from traditional alloy steels, which are prone to softening at high temperatures. However, the temperature ranges for the preservation of hot hardening in RATE steels was not systematically studied, which makes it difficult

Abstract:

The work hardening of Al alloys is very important in regards to their formability and their deformation behavior in service. The majority of the work in the literature has considered relatively pure materials, and has tended to concentrate on room temperature and elevated temperature behavior. In Al alloys there is interest in work hardening at lower temperatures since they are quite restricted in terms of the elevated temperatures at which they can be used. In this paper the work hardening of commercial 1000, 3000 and 5000 alloys have been investigated from room temperature down to 85°K. The

Abstract:

Abstract Stainless steels are commonly used for high precision components, which often are exposed to corrosive media. However, their inferior tribological behaviour restrict the use of these materials in many technical applications. Thermochemical surface hardening is one way to overcome these weaknesses. Solution nitriding in the austenitic range above 1000 °C is mainly used for hardening martensitic and ferritic stainless grades. In austenitic and duplex stainless grades, however, the hardening effect is limited. Additionally, the high process temperatures combined with a necessary rapid co

Abstract Aiming at the problem of damage evolution of pure copper during the plastic deformation, the normalized shape factor is introduced based on the RO model (Ramberg-Osgood model).

The results show that the error between the calculated value and the experimental value of the damage constitutive model, based on normalized shape factor, at different annealing temperatures, is less tha

Tensile specimens irradiated to 0.002, 0.029, and 0.046 dpa exhibited significant increases in the strain-hardening exponent with increasing neutron irradiation level.

In the automotive industry, press hardening is usually employed to produce safety orstructural components from advanced high–strength steels. This hot forming process, andthermomechanical forming processes in general, is highly dependent on friction betweentool and workpiece as friction affects and controls the deformation of the workpiece.However, friction is also directly associated with wear of the forming tools. Tool wear isa complex system response depending on contact conditions and is a serious issue whenit comes to process economy as it reduces the service life of the tool. Therefore,

These alloys are heat-treatable and their strength depends to a large extent on the quenching and aging steps of the heat treatment process.

Abstract:

Cement hydration is the result of a series of simultaneous chemical reactions occurring during the production of concrete. An excessive amount of heat is generated, which consequently may give rise to thermal stresses and cause early age cracks in concrete that may affect its structural integrity, and load bearing capacity. Incorporating fly ash into the concrete mixture has shown to be an efficient method to reduce the temperatures developed during early age hydration, especially for massive concrete structures. Fly ash does additionally affect the concrete's development of compressive streng

The automotive industry currently demands materials with improved formability and crash performance. Austenitic stainless steels have been singled out for potential development of high strength steels to achieve exceptional combinations of strength and ductility due to their high strain hardening abilities. Austenitic 301LN stainless steel is the least alloyed and most metastable among the 300-series austenitic stainless steels. Plastic deformation at a temperature below Md transforms the metastable austenite phase to a thermodynamically more stable martensite phase accompanied with enhanced s

AbstractModels for precipitation hardening (PH) at room temperature have been available for a long time. In spite of the importance of PH, it took a long time to establish models for elevated temperatures. In fact, empirically the room temperature models have also been used at higher temperatures. This gives the wrong temperature dependence and overestimates PH. It was for a long time thought that it was an energy barrier for climb across particles that was the controlling mechanism, but it was gradually appearing that this effect was so small that it could be neglected.

The structure and properties of the obtained coatings are examined. The coatings permit improving substantially the service life of cutting tools.

Abstract:

If a relationship between the deformation properties of a line pipe steel and its stress-corrosion cracking resistance can be established, then steels may be selected or designed for improved stress-corrosion resistance, based on their mechanical properties. Benefit: In this research program three line pipe steels, removed from long-term service, were examined to determine if there is a correlation between their mechanical properties and stress-corrosion cracking resistance. The hypothesis was that the steel with the greatest tendency for strain hardening, under cyclic and monotonic stress con

Abstract:

The application of bio-oils in asphalt and polymer-modified asphalt (PMA), has recently received considerable attention as a pivotal method for enhancing the high-temperature performance of asphalt mixtures while maintaining good binder’s workability. In this study, Jatropha curcas oil (JCO) was selected and evaluated as an PMA modifier. JCO-rHDPE-modified bio-asphalt was prepared with different JCO contents: 1, 3, and 5 wt.%. Physical tests (penetration, softening point, and ductility), rheological tests (dynamic viscosity and rolling thin-film oven test–RTFOT), and thermogravimetric analysis

Abstract:

Truck platoons are expected to improve safety and reduce fuel consumption. However, their use is projected to accelerate pavement damage due to channelized-load application (lack of wander) and potentially reduced duration between truck-loading applications (reduced rest period). The effect of wander on pavement damage is well documented, while relatively few studies are available on the effect of rest period on pavement permanent deformation. Therefore, the main objective of this study was to quantify the impact of rest period theoretically, using a numerical method, and experimentally, using

Abstract:

Welding of micro-alloyed, high strength steels such as X100 poses a number of challenges due to, in part, the sensitivity of weld mechanical properties to the welding parameters such as heat input, preheat temperature, etc. For design purpose, it is often required that the mechanical properties of the welds overmatch those of the pipe materials in terms of yield strength, ductility, and toughness. In general, high strength pipe steels exhibit lower strain hardening capability, lower ductility, and increased anisotropy than the traditional lower grade steels. For these steels, when exposed to w
