热处理铸造活塞的使用寿命,在很大程度上取决于材料的初次结晶条件。本文的目的,是探讨提高活塞硬度的可能性与类似AK18铝合金的国外合金(Mahle138,K 5 281;L M3o等)的特点。
The life of heat-treated casting pistons depends very much on the initial crystallization of the material. The purpose of this paper is to explore the possibility of increasing the hardness of the piston and the characteristics of a foreign alloy such as AK18 aluminum alloy (Mahle 138, K 5 281; L M3o, etc.).
