Abstract
Along with growth of conventional PM (Powder Metallurgy) industry, advanced PM technologies like wrought PM aluminum alloys, super plastic super alloy, mechanically alloyed ODS alloys seemed attractive for the industry to have further growth. New materials and processes that fit to Japanese automotive and appliance industries have been developed inspired by the advanced PM technologies.
PM Al-Si-X alloys that adapt to iron and steel structure were developed. For improved economics and NNS (Near Net Shape) formability, encapsulation-free Powder Extrusion process and coining type Powder Forging process were developed. Based upon these technologies, more functional new materials than simple structural materials were also developed, for example light weight heat sink and high performance engine cylinder liners.
