【摘要】 船舶、坦克用柴油机的排气阀主要采用Nimonic 80A锻制而成。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 valves of diesel engine on ships,airplanes and tanks are mainly made of Nimonic 80A by forging.This kind of material possesses excellent heat-resistant property,high strength and large resistance to deformation at high temperature,so it is very difficult to be deformed.A practical forging process in a die was put forward in present paper.更多还原
