【Abstract】 W based heavy alloys of three different compositions were prepared by using metal injection moulding technology (MIM), emphasing to the debinding and sintering processes. The effects of sintering temperature on mechanical properties, fracture surfaces and microstructure were analysised. Sintering shrinkage, mechanical properties and the optimized sintering temperatures were also presented.更多还原
