最近の自動車用材料における粉末冶金技術の動向

抄録

Today's trends of powder metallurgy in automotive materials are mainly on high strenght P/M materials, cost effective way and special use P/M materials.
In this paper, we would like to show the technical topics of these trends;
(1) P/M forgings for high strength structural P/M materials.
(2) Utilization of cast iron swarf as lower cost powder.
(3) Cold P/M forging technique.
(4) Trends of aluminum P/M.
(5) Super wear resistant materials for engine.
