川崎制铁等开发出以低成本制造复杂形状部件的烧结冷锻法。该方法以粉末冶金铁粉为原料 ,可以制造高密度的复杂形状部件。其主要工艺为 :铁粉预备成型—预备烧结—冷锻烧结—冷锻—正式烧结—(热处理 )。由于用粉末的模型成型 (预备成型 )制造材料 ,锻造成型简化 ,使得设计材料

Kawasaki Steel and others have developed a sintered cold forging method for manufacturing complex-shaped parts at a low cost. The method uses powder metallurgy iron powder as a raw material to manufacture high-density complex shaped parts. The main process for the preparation of iron: pre-sintering - cold forging sintering - cold forging - the official sintering - (heat treatment). Since the material is produced by molding (pre-molding) the powder, the forging molding is simplified so that the design material
