粉末冶金学的发展使我们能够成功地利用粉末材料生产重负荷的重要零件。包括一些目前用低合金钢模锻的零件的生产,也能够用粉末冶金学的方法得到毛坯,而最后的形状和要求的密实性则用精密的热模锻获得。这样的工艺过程兼有粉末材料成本的优点和模锻的金属构件的高质量。生产消耗的降低是靠省掉目前为了获得精锻件所必须的那 The development of powder metallurgy has enabled us to successfully produce the most important heavy-duty parts from powder materials. Including the production of parts that are currently forged with low-alloyed steels, as well as powder metallurgy, and the final shape and densification required are precision hot forged. Such a process combines the advantages of the cost of the powdered material with the high quality of the swaged metal components. The reduction in production costs is achieved by eliminating the current need for precision forgings
