Since the introduction of warm compaction in 1994, several new warm-compacted powder metallurgy (P/M) parts have been developed. However, the main applications to date have been limited to machine tool parts and parts for agricultural tools, for example. Only a few automotive parts have been developed by using the warm-compaction method. Engine parts have not yet to be developed, particullary. Here, we investigate the mechanical properties and wear resistance of warm-compacted P/M materials, and the developed warm-compacted P/M engine sprockets. A method of controlling the powder temperature is also described.
