烧结硬化可以提高生产效率,节约生产费用,设计烧结硬化合金的成分既要充分考虑到冷却时有利于形成马氏体组织的需要,又要兼顾合金的成本,根据这个原则近年开发出了一些新的烧结硬化合金。粉末冶金钢的硬化性能是用来衡量合金烧结硬化的一个重要指标,乔米尼(Jominy)末端淬火普遍 Sintering hardening can improve production efficiency, save production costs, the design of sintered hardened alloy composition should take into account both the cooling is conducive to the formation of martensite needs, but also take into account the cost of the alloy, according to this principle in recent years developed a number of new Sinter-hardened alloy. The hardenability of powder metallurgical steels is an important indicator of the sintering hardening of alloys. Jominy end quenching is common
