粉末锻造是粉末冶金技术领域中最近几年发展起来的一项新工艺。它兼有粉末冶金和锻压成形的特点,可以制造外形复杂和强度要求高的零件。同机加工和钢的模锻、挤压相比,简化了工序,减少了切削量及加工设备,提高了材料的利用率(一般在90%以上)。因此,正获得迅速的发展[1]、[2]。我厂在上级领导的大力支持及上海汽车齿轮厂等兄弟单位的协助下,于1971年开始用粉 Powder forging is a new process developed in the field of powder metallurgy in recent years. It combines the power of powder metallurgy and forging to create parts that require complex shapes and high strength. Compared with machining and steel forging, extrusion, simplifying the process, reducing the amount of cutting and processing equipment, improve the utilization of materials (generally more than 90%). Therefore, rapid development is gaining [1], [2]. I plant in the higher leadership and the strong support of Shanghai Automotive Gear Factory and other brothers units with the assistance of the powder in 1971 began
