摘要
本文主要用TEM和相分析对几种V、Ti微合金钢析出相进行了形貌观察和定性、定量分析,研究了V、Ti微合金钢的析出特性及其对强度、塑性及韧性的影响,这对优化合金设计及微合金钢强韧化机制研究有十分重要的意义。
The precipitates of several V and Ti microalloying steels were observed under TEM and analyzed quantitatively with an APD-15 X ray diffractometer. The precipitation behaviour and its effects on strength, plasticity and toughness of the steels were studied. This is of significance to optimization of alloy design and study of mechanisms of strengthening and toughening in microalloying steels.
