PROGRESS AND PROSPECT OF RESEARCH AND APPLICATION OF POSDER METALLURGY PROCESSES OF MO AND LTS ALLOYS

The extensive investigations in recent years on the research progress and industrial application of powder metallurgy processes of Mo and its alloys are reviewed. Powder metallurgy fundamentals of Mo, preparation processes of super -fine and nano Mo powder, Mo powder with big particle size or/and excellent flowability, and high - purity Mo powder （including vapor phase reduction, activated reduction, carbonyl pyrolytic process, microwave plasma, microwave plasma chemical vapor deposition, hybrid plasma reduction process, mechanical alloying, mechanical atomization technology, plasma atomization technology, plasma physical vapor deposition, and several modified processes）, up - to - date compaction processes of Mo （ including magnetic compaction process, warm compaction, warm flow compaction （WFC）, high velocity compaction （HVC））, nearly developed sintering processes of Mo （including SPS, selective laser sintering （SIS）, continuous microwave sintering）, and some new progresses in the numerical simulation methods of the P/M processes, are respectively described in detail. And the fundamentals, features, equipment, application and prospects of the processes are evaluated.
