Metal matrix composites of Al-WC (10, 15 and 20 wt%) were prepared by microwave (without holding) and conventional sintering (held for 1 hour) processes at various temperatures between 650-950 °C. The results indicated that the highest density of conventional and microwave sintering corresponds to
Additionally, commonly used graphite tooling for pellet fabrication was shown to be ineffective in producing large numbers of fuel pellets, as the die and punches were shown to undergo severe wear in each run thus decreasing the reliability of the tooling for production of pellets as per the specification.
Boron carbide is the third hardest material and can be used as the better choice for the selection of reinforcement. Graphite particulates are also be used as a reinforcement, as their addition improves the machinability and wear resistance  of Al-SiC composites. The method of fabrication affects the
Dies are made of cemented carbide, die/tool steel; pressed using hydraulic or mechanical presses The basic purpose of compaction is to obtain a green compact with sufficient strength to withstand further handling operations The green compact is then taken for sintering Hot extrusion, hot pressing, hot isostatic pressing => consolidation at high
VACUUM FURNACES FOR SINTERING WITH DEWAXING. To achieve a high density and to remove gases and contaminants with preliminary sintering and removal of the binder, the vacuum sintering furnace with dewaxing of casting metal under pressure can be performed in a gas atmosphere where muffle gas output will remove binders or other outgassing products, preventing them contact with the heating element
A new processing strategy based on atmospheric pressure sintering is presented for obtaining dense SiC‐based materials with microstructures consisting of (i) uniformly distributed elongate‐shaped α‐SiC grains and (ii) relatively high amounts (20 vol%) of second‐phase yttrium aluminum garnet (YAG).
High Temperature Carburization; Preparation of the W+C blend is the same for this type of carburization as for the conventional type. The main difference with respect to the foregoing method is the carburization temperature ranging between 1800℃ and 2200℃.
2016426The invention claimed is: 1. A process for fabrication of a SiC-based article, comprising: preparing an aqueous suspension of SiC powder with a first amount of water soluble titanium compound that is convertible to TiO 2 by thermal decomposition, a second amount of water soluble carbon source, a third amount of boron carbide powder and a binder; drying the aqueous suspension to obtain a powder
The effect of Al addition on pressureless sintering of B 4 C ceramic was analyzed in the present work. Different amounts of Al, from 0 to 5 wt.% were added to the base material and pressureless sintering was conducted at 2050 and 2150 °C under argon atmosphere.
