研究了含铝TRIP钢在相同的热处理条件和不同冷轧压下率时的组织和力学性能。结果表明,随着冷轧压下率增加,材料组织细化,屈服强度连续升高;而抗拉强度和伸长率则由于晶粒细化以及TRIP效应,先升高后降低。冷轧压下率74%时材料的综合性能最佳,此时带状组织的危害也有所减轻或消失。 The microstructure and mechanical properties of TRIP steel containing aluminum under the same heat treatment conditions and different cold rolling reduction rates were investigated. The results show that with the increase of cold rolling reduction, the microstructure of the material is refined and the yield strength increases continuously. However, the tensile strength and elongation increase first and then decrease due to grain refinement and TRIP. When the cold rolling reduction rate of 74%, the best overall performance of the material, this time the harm of banded tissue has also been reduced or disappeared.
