摘要
本文对影响稀土-镁球铁正火态组织的耐磨性因素进行研究。研究结果表明:正火态组织耐磨性取决于珠光体量和珠光体加工硬化率的大小,后者是提高耐磨性的主要方面。
This paper deals with the effect of structure of normalizied Re-Mg Nod-ular Iron on its wear resistance. The research result shows that the wearresistance of normalized nodular iron by depends on the quantity of pearliteand strain harden ability, of which the latter would be main one for impro-ving the wear resistance.
