摘要
矿用设备中采用高锰钢部件颇多。提高这些部件使用寿命的途径之一是应用先进的爆炸预硬方法。文中对高锰钢爆炸硬化机理所作实验研究表明!晶粒细化、位错、堆垛层错和孪晶的产生是导致硬化的主要原因。
High Mn steel finds wide use in the manufacture of mining machinery components. One way to extend the service life of these components is pre-hard-ening by explosion. Experiments conducted on the hardening mechanism of explosion hardening of high Mn steel show that the formation of dislocation,occurrance of stacking disorder,of twins and refinement of the grain particles are main factors leading to the hardening.
