| 摘 要： | 随着常规粉末冶金产业发展，像锻轧粉末冶金铝合金、超塑性高温合金、机械合金化氧化物弥散强化（ODS）合金之类的先进粉末冶金工艺，引起了人们的注意。受先进粉末冶金工艺启发，开发了适应日本汽车与家电产业的新材料与生产工艺，开发了适合于钢铁结构的粉末冶金Al-Si-X合金。为了改进经济性与近终形（NNS）成形性，开发了无包套粉末挤压工艺与精压式粉末锻造工艺。基于这些工艺，还开发了比单一结构材料具有较多功能的新材料，诸如轻量散热器（heat sink）与高性能发动机气缸内衬。

| Abstract: | Along with growth of conventional PM(Powder Metallurgy)industry,advanced PM technologies like wroguht 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. |
