高强中锰TRIP钢的残余奥氏体含量及其稳定性
Content and Stability of Retained Austenite in High Strength Medium-Mn TRIP Steel
摘 要
设计了一种中锰相变诱导塑性(TRIP)钢, 利用全新的热处理工艺对其进行处理, 研究了其残余奥氏体含量及其稳定性, 并对该钢的显微组织和力学性能进行了分析。结果表明: 中锰TRIP钢退火后的残余奥氏体体积分数均在39%以上, 且奥氏体在变形过程中绝大部分转变为马氏体, 提高了钢的塑性和强度; 在630 ℃退火可使该钢的抗拉强度大于1 000 MPa, 伸长率大于30%, 强塑积大于30 GPa·%, 残余奥氏体体积分数为51.4%。

Abstract
A desinged medium-Mn transformation-induced plasticity (TRIP) steel was treated by a new heat treatment, the content and stability of retained austentite were studied, the microstructure and mechanical properties of the steel were analyzed. The results show that the volum fractions of retained austenite contents in the medium-Mn TRIP steel after annealing were all over 39%, and they almost transformed into martensite during deformation process and thus increased the plasticty and stregth of the steel. The tensile strength(σb), elongation δ and σb·δ respectively were over 100 MPa, 30%, 30 GPa·%, and volume fraction of retained austenite was 51.14% after annealing at 630 ℃.
