粉末冶金是一门制造金属粉末或用金属粉末(添如或不添加非金属粉末)经过成形、烧结而制取各种金属材料和制品的技术学科,是材料工程学的一个重要领域。它巧妙地将材料制造技术与金属成形技术结合起采,形成一门独特的技术。用这种技术制造的材料和制品,不仅具有优异的组织和性能,并且技术经济效果显著。因此,粉末冶金技术在本世纪内获得了蓬勃发展。
Powder metallurgy is an important field of material engineering, which is a technical discipline for manufacturing metal powder or metal powder (with or without nonmetallic powder) through forming and sintering to make various metal materials and products. It cleverly combines the materials manufacturing technology with the metal forming technology to form a unique technology. Materials and articles made with this technology not only have excellent microstructure and properties, but also have significant technical and economic benefits. As a result, powder metallurgy technology has thrived during this century.
