Abstract:

This paper is focussed on the development of microstructure during liquid phase sintering and post-densification crystallisation heat treatment of ceramic materials based on the α- and β-Si3N4 structures. Grain shape and size distributions, assessed by quantitative microscopy in combination with stereological methods, and fine scale microstructures, investigated by electron diffraction and high resolution imaging and microanalysis in the transmission electron microscope, are discussed in relation to the fabrication process and the overall composition of the ceramic material.

Abstract:

Nicalon SiC fibre tows have excellent properties for ceramic matrix reinforcement but residual oxygen within the fibres degrades fibre properties when these are incorporated into ceramic matrices at elevated temperatures. β-SiAlON ceramics also have excellent mechanical and physical properties, especially fracture toughness. However, sintering of β-SiAlON is generally carried out at 1650-1750°C, considerably higher than the temperatures above which fibre degradation occurs (>1200°C). In the present study, the refractoriness and strength of Nicalon fibres were improved by high pressure CO heat treatment, and densification temperatures of β-SiAlON were lowered by using different kinds of sintering additives. Heat-treatment of the fibres under 45 bar CO pressure at 1500-1650°C led to an increase in fibre strength and to the formation of a thin carbon layer on the surface of the fibres. These improvements in the Nicalon SiC fibres allowed them to be incorporated successfully into β-SiAlON matrices. The as-received and heat-treated fibres were infiltrated with β-SiAlON starting powder mixes and hot-pressed with low temperature sintering additives at 1600-1700°C for 30 min. Bending strength and fracture toughness measurements showed that samples containing heat-treated fibres provided a significant strength and fracture toughness increase compared with similar samples prepared using as-received fibres, and massive pull-out was observed because of the weak interface resulting from the surface carbon coating on the fibres.

Abstract:

This paper is focussed on the development of microstructure during crystallisation heat treatment of B-phase parent glasses with composition (e/o) 35R:45Si:20Al:83O:17N, where R = Er, Yb, Y or a mixture of Y and Yb. Extensive high resolution analytical transmission electron microscopy has shown that the lenticular B-phase crystals take up a substantial range of composition. The element R is always clearly anti-correlated with the Si, and a larger R3+ cation radius moves the composition range to lower R contents. It is suggested that a locally increased density in the bi-dimensional network of randomly oriented (Si,Al)(O,N)4 tetrahedra is associated with an increased density of vacancies in the R3+ cation lattice.

Abstract:

Y-α-sialons (Y0.333Si10Al2ON15) were prepared by hot pressing using 5 wt.% BaAl2Si2O8 as an additive. The results showed that barium aluminosilicate not only.served as a liquid-phase sintering aid to promote densification, but also facilitated the.development of elongated α-sialon grains. The obtained self-toughened α-sialon was.both hard and tough. The Vickers hardness, flexural strength, and fracture toughness.are 18.9 GPa, 802 MPa, and 6.0 Mpam1/2, respectively. Post heat treatment could.promote the growth of elongated α-sialon grains, hence further increasing its.toughness.

Abstract:

Si3N4based ceramics are widely researched because of their low density, high hardness, toughness and wear resistance. Post-sintering heat treatments can enhance their properties. Thus, the objective of the present paper was the development of a Si3N4based ceramic, suitable for structural applications, by sintering in nitrogen gas pressure, using AlN, Al2O3, and Y2O3as additives and post-sintering heat treatment. The green bodies were fabricated by uniaxial pressing at 80 MPa with subsequent isostatic pressing at 300 MPa. The samples were sintered at 1900°C for 1 h under N2gas pressure of 0.1 MPa. Post-sintering heat treatment was performed at 1500°C for 48 h under N2gas pressure of 1.0 MPa. From the results, it was observed that after post-sintering heat treatment there was a reduction of α-SiAlON phase and increase of β-Si3N4phase, with consequent changing in grain size, decrease of fracture toughness and increase of the Vickers hardness.

Abstract:

(Y + Sm)–α-sialon compositions with and without α-sialon seeds were hot-pressed at 1800 °C for 1 h and then heat treated at 1800 °C for 4 h. The effect of α-sialon seeds on the microstructures of (Y + Sm)–α-sialon ceramics was studied by scanning electron microscopy. The results showed that hot-pressed α-sialon ceramics with elongated grains can be fabricated by adding 10 wt% seeds. Through heat treatment, the seed-free composition could also develop into a similar microstructure with big elongated grains dispersed in a fine matrix.

Abstract:

Sialon ceramics (Si-Al-O-N) are high performance engineering materials used as cutting tools and wear parts whose performance may be compromised by high temperature oxidation. Ion Beam Analysis (IBA) techniques, coupled with X-ray Diffraction, have been used to monitor oxidation processes in dense bodies of α/β-sialon, X-sialon and O-sialon subjected to heat treatment schedules in air to induce surface oxidation. This has permitted depth profiling of Si, Al, Y, O, & N in the sialon bodies, enabling direct comparison of oxidation resistance to be made between the different sialon compositions.

Abstract:

Tribological performance of technical ceramics is influenced by various factors. Among the others the material properties, loading conditions, residual stresses as well as chemical reactions and interaction between contacting parts effect the damage process. The current paper focuses on the material features, investigating the possibility of modifying the wearing characteristics of a Si3N4 based technical ceramics by post-heat treatment. The microstructure, the mechanical properties and the wearing characteristics were studied on HIP-sintered SiAlON samples, post heattreated in oxidizing atmosphere at different temperatures. Wearing performance was characterized by pin-on disc tests. The wear rate varied with the temperature of heat treatment. From tribological point of view especially treatment at 1200°C proved to be advantageous Microstructural investigations by TEM and X-ray diffraction studies revealed some explanations of these changes. The above studies were completed by mechanical tests. Microhardness, E-modulus, four point bending strength and indentation fracture toughness have been determined in order to study the correlation between the tribological and mechanical properties. Based on our results, the post heat treatment may be useful to improve the wearing performance of SiAlON ceramics.

Abstract:

Recently we have introduced a novel processing concept of sialon components implying that an extra liquid phase that is thermodynamically compatible with sialon phases is introduced by increasing the O/N ratio in the general formula (Yb+Y)xSi12-(3x+n)Al3x+nOnN16- n while keeping constant the Yb, Y, Si, and Al proportions. By increasing the oxygen content from its stoichiometric value of 5.16 to 15 eq%, a series of powder mixtures were prepared and their overall compositions are located slightly above the homogeneity region of the a- sialon phase. These compositions were consolidated to full densities by hot pressing (HP) and Spark Plasma Sintering (SPS), respectively. The sintering kinetics in the HP and SPS units is compared. The grain growth kinetics were investigated both by post heat-treatment of SPS pre-consolidated monophasic a-sialon bodies consisting of sub-micron sized equiaxed grains in a conventional graphite furnace using extended holding times (hours) and in the SPS apparatus rapidly heated exceeding the temperature threshold of grain growth and using short holding times (minutes). Post heat treatment in the SPS apparatus yielded in-situ reinforced microstructures no matter if an additional liquid/glass was involved or not while corresponding microstructures could only be obtained for non-stoichiometric compositions by post heat treatment in the graphite furnace. The grain growth kinetics is discussed in terms of static and dynamic ripening mechanisms. We have recently shown that the ductility of covalent bonded silicon nitride based ceramics is dramatically enhanced in presence of a pulsed electric field. Compressive strains rates in the range of 10-2 s-1 can easily be achieved at T ³ 1500oC. The enhanced ductility is explained by that the electric field induces motion of charged species present in the grain boundary glassy/liquid phase that in turn promotes grain sliding along the grain boundaries.

Abstract:

Dual cation (Yb + Y)-stabilized α-sialon ceramics with either stoichiometric composition or nonstoichiometric composition that yield less than 3 vol% of an additional intergranular liquid/glass phase were consolidated by spark plasma sintering (SPS). This process allows very fast heating and cooling, thus providing a unique possibility to monitor and manipulate the kinetics of phase transformation and grain growth during sintering. Below a temperature threshold, full densification and complete α-sialon formation are accompanied by very limited grain growth. The grain growth kinetics were investigated both by post heat-treatment of SPS pre-consolidated monophasic α-sialon bodies consisting of sub-micron sized equiaxed grains in a conventional graphite furnace using extended holding times (hours) and directly rapid annealing in the SPS apparatus above the temperature threshold (within minutes). Post heat treatment in the graphite furnace yielded in situ reinforced microstructures consisting of interlocking elongated grains only in the presence of an additional intergranular liquid/glass phase. Direct annealing by SPS process yielded in situ reinforced microstructures whether or not an additional liquid/glass was involved. The former microstructures are formed via the static Ostwald ripening mechanism whereas the latter ones are generated via a dynamic ripening mechanism. This demonstrates that the dynamic ripening provides an efficient means of developing in situ reinforced microstructure in α-sialon ceramics with improved mechanical properties.

Abstract:

The effect of nitrogen gas flow rate on the morphology of silicon nitride fibers obtained via carbothermal nitridation heat treatment method was investigated. A precursor containing silicon, oxygen and carbon was obtained by a sol-gel method from a mixture of tetraethyl orthosilicate, polyvinyl alcohol, H2O and ethanol. A white wool-like product was obtained by heat treating the precursor placed in an alumina crucible under a 0.5 MPa nitrogen gas pressure at 1500oC with different nitrogen gas flow rates. The mass-based production rates of the samples obtained from the precursor powder were 20-30% for the different nitrogen gas flow rates. X-ray diffraction analysis revealed that the samples contained α-Si3N4 as the major phase along with β-Si3N4, Si2N2O and a small amount of amorphous product as minor phases. Unique twisted fibers with diameters of several hundreds of nanometers were found among the straight fibers by SEM observation. Elemental analysis using energy dispersive X-ray spectroscopy indicated that silicon and nitrogen were contained in the twisted fibers along with approximately 68 at.% of oxygen and several at.% of aluminum, which might have come from the crucible material. The SiAlON-like structures might have been formed by the partial dissolution of Al and O in the Si3N4 fibers. It was considered that the twisted morphology of some fibers might be formed by co-existing of β-SiAlON and/or amorphous phase regions in the Si3N4 fiber and resultant distortion of the fibers.

Abstract:

Eu-doped SiAlON thin films were successfully prepared by co-sputtering method using [Formula: see text]-SiAlON and Eu2O3 ceramic target. The photoluminescence behaviors of the films are investigated as a function of Eu ions concentration and temperature. The doping concentration of Eu ions in films can be effectively controlled by adjusting the sputtering power of Eu2O3 target. XRD analysis and SEM morphology images illustrate that the Eu-doped SiAlON thin films are amorphous, dense, and smooth, no matter they experienced high temperature heat-treatment or not after co-sputtering deposition. An intense and broad blue emission band peaking at 416–450[Formula: see text]nm was exhibited when the films upon excitation at 275[Formula: see text]nm, proving a typical Eu[Formula: see text] emission. The divalent state of Eu ions in films was further identified. As the sputtering power of Eu2O3 target increases, the emission peak of Eu[Formula: see text] shows a red-shift. The prepared thin films possess a better resistant property of thermal quenching and the relative fluorescence intensity at 100∘C can remain about 86% of its initial value at room temperature.

Abstract:

At temperature above 1200°C, the thermal stability of α-SiAlON phases has been debated since 1992; however, it has been discussed if any α-SiAlON phase can be formed in Ce, La, Eu and Sr-doped SiAlON systems. In our previous studies it was shown that the use of Mg-Ce and Mg-Sr elements as dopants SiAlON compositions, in which all elements just have very low or no stability in the α-SiAlON structure, would promote the stability of Mg-Ce elements in the α- SiAlON phase [1, 2]. However, in Mg-Sr systems, it was obtained that Mg2+ is predominantly incorporated in α-SiAlON structure whereas Sr2+ mainly remains in the grain boundaries [2]. In this study, by applying spark plasma sintering (SPS) (at 1400-1700°C) and post-sintering thermal heat treatment (at 1500°C for 5 hrs and 1700°C for 2hrs) Mg or Mg-Sr doped SiAlON (50:50 mole ratios) ceramics were prepared. The results were compared with GPS sintered samples data. The effect of sintering temperature on densification process, phase transformation, microstructure and mechanical properties of samples were investigated. The results showed that by using SPS, Sr-Mg doped samples can be sintered at lower temperature (at 1600°C) than at GPS (at 1800°C) and it has no Sr-doped grain boundary phases.

Nd-doped α-SiAlON starting composition (Nd0.33Si9.38Al2.62O1.62N14.38) was prepared by gas pressure sintering at 1825°C for 3 hrs. In order to explore the effect of post heat treatment on the developments of elongated α-SiAlON grains, sample was heat treated at 1800°C for 4-12 hrs. It was found that post heat treatments promoted formation of the elongated α-SiAlON grains. The controlling mechanism of grain growth was determined via plotting on a graph the growth in width/length versus time graphics using Image Analysis method. Different growth rates were found between the length and width direction of the α-SiAlON crystals, resulting in anisotropic grain growth in the microstructural development.

Abstract:

β-Sialon/Si3N4composite ceramic were prepared from starting materials of α-Si3N4, AlN and Al2O3by pressureless sintering. The physical properties, phase composition and microstructure were tested by modern testing technology. The effect of different additives such as Y2O3, La2O3and borax on the sintering temperature and physical properties was studied. The results show that D3 is the best formula, firing shrinkage rate of the sample is 14.14%, water absorption 3.16%, porosity 9.02%, bulk density 2.85g·cm-3and bending strength 193.87MPa after firing at 1580°C. XRD analysis indicates that the main phases of D3 are β-Sialon, β-Si3N4and corundum. SEM analysis shows that the microstructure of D3 sample is quite dense and the pores distribution is uniform, the diameter of the pore is about 1~5μm. β-Sialon/Si3N4composite ceramic has high bulk density, bending strength and fine microstructure, which is a new choice of the heat absorb material for solar thermal power generation system.

Full text

Abstract:

The microstructure of a microwave-densified silicon nitride based ceramic has been assessed in the as-sintered, post-sinter hot-isostatically pressed (HIPed) and annealed conditions. The grain size of the as-sintered material, which is a low substitution β′-Sialon, was significantly finer than observed in conventionally processed materials of similar composition. The as-sintered ceramic exhibits a reverse porosity gradient (with the highest porosity level at the surface) due to heat dissipation to the cooler surroundings during microwave processing. This also results in a higher β′ aspect ratio close to the surface arising from an increased glass viscosity (due to heat loss) and compositional change in this region during sintering. HIPing results in removal of all porosity from the sample core; however, a reduced porosity surface layer is retained. Significant β′-Sialon grain growth is also apparent after HIPing. A fine β′ grain structure was retained after annealing, with partial devitrification of the glassy grain boundary phase to β-Y2Si2O7.

Abstract:

Due to their high hardness and wear resistance, Si3N4 based ceramics are one of the most suitable cutting tool materials for machining cast iron, nickel alloys and hardened steels. However, their high degree of brittleness usually leads to inconsistent results and sudden catastrophic failures. This necessitates a process optimization when machining superalloys with Si3N4 based ceramic cutting tools. The tools are expected to withstand the heat and pressure developed when machining at higher cutting conditions because of their high hardness and melting point. This paper evaluates the performance of α-SiAlON tool in turning Ti–6Al–4V alloy at high cutting conditions, up to 250 m min−1, without coolant. Tool wear, failure modes and temperature were monitored to access the performance of the cutting tool. Test results showed that the performance of α-SiAlON tool, in terms of tool life, at the cutting conditions investigated is relatively poor due probably to rapid notching and excessive chipping of the cutting edge. These facts are associated with adhesion and diffusion wear rate that tends to weaken the bond strength of the cutting tool.

Abstract:

Baja karbon rendah merupakan material yang biasa digunakan dalam industri penanganan batu bara, tapi memiliki ketahanan erosi dan korosi yang rendah. Oleh karena itu, dilakukan pelapisan ceramic coating berpengikat fosfat. Al(OH)3 dan H3PO4 digunakan sebagai bahan dasar binder. Partikel ceramic yang digunakan adalah Al2O3 dan SiC. Pada pembuatan ceramic coating berpengikat fosfat ini dilakukan heat treatment selama 1 jam, 3 jam dan 5 jam untuk mengetahui pengaruh waktu heat treatment terhadap karakteristik ceramic coating. Pengamatan menggunakan SEM menunjukkan semakin lamanya waktu heat treatment semakin banyak vacancy yang terbentuk. Dilakukan pengujian erosi untuk mengetahui ketahanan erosi ceramic coating dan hasil pengujian menunjukkan nilai erosion rate ceramic coating dengan partikel SiC sebesar 7,5 mg/Kg dan tanpa partikel SiC sebesar 14,2 mg/Kg. Kemudian dilakukan pengujian ketahanan air, didapatkan losses dari ceramic coating sebesar 0,074%. Hasil dari keseluruhan karakterisasi yang dilakukan menunjukkan, bahwa semakin lama waktu heat treatment ketahanan erosi dan ketahanan air meningkat pada rentang waktu heat treatment 1 – 5 jam.

Abstract:

A new kind of machinable glass-ceramic was prepared by the sintering methods which has the high KIC, flexural intensity and other good mechanical properties so that it could be machined using the normal machinable methods such as turning, milling and drilling. The hardness and flexural intensity which was the main mechanical property factor influenced the machined ability was researched in detail with the help of TG-DSC, SEM, metalloscope, Hv hardness and flexural intensity measurements. Based on the orthogonal design methods (L2554) and numerical solution, the effects of the heat treatment about devitrification on the mechanical properties were analyzed and concluded that the mechanical properties was mainly influenced by the crystal temperature and heat holding time.
