粉末锻造是七十年代末冶金工业领域中的新技术.早在四十年代,美国通用汽车公司就发表过关于粉末热锻的报导,但是直到七十年代,随着粉末冶金制品向高强度结构零件的发展的要求,随着雾化预合金粉的出现及粉末价格的不断降低,粉末锻造受到越来越大的重视,被认为是粉末冶金领域中划时代的发展.也就是说,粉末锻造是粉末冶金摆脱局限于制
Powder forging is a new technology in the metallurgical industry in the late seventies.As early as the 1940s, General Motors Corporation published reports on powder hot forging, but it was not until the 1970s that as powder metallurgy advanced to high-strength structures With the development of parts, with the emergence of atomized pre-alloy powder and the continuous decrease of the price of powder, powder forging has received more and more attention, which is considered to be an epoch-making development in the field of powder metallurgy. Powder metallurgy to get rid of the limitations of the system
