【摘要】 船舶、飞机、坦克用柴油机的排气阀主要用Nimonic 80A锻成。Nimonic 80A具有很高的耐热性能,在高温下强度高,变形抗力大,增加了锻造成形的难度。本文通过研究试验,提出了一套切实可行的胎模锻造成形方法。更多还原

【Abstract】 The exhaust valve of diesel engine on ship,airplane and tank is made of Nimonic 80A by forging. Because this material possess the higher heat resistant property ,and resistance to deformation is very large under the higher temperature, so it is very difficult to deform. This paper put forward a forging process in a die.更多还原
