通过热模拟压缩实验,研究了基于过冷奥氏体动态相变的C-Mn-Al-Si系热轧TRIP钢的组织演变规律.结果表明,在过冷奥氏体动态相变过程中,铁索体相变速率较快,生成铁索体的体积分数与应变量有着一定的对应关系,铁素体晶粒细小且未相变的奥氏体更加分散.在贝氏体等温处理时,过冷奥氏体动态相变后较大尺寸的奥氏体能够较快地发生贝氏体相变,但生成的贝氏体束尺寸较小,位向较为混乱;而位于相邻铁素体晶粒间,尺寸在0.5-1.5μm之间的细小奥氏体岛稳定性较高,不易于发生贝氏体相变.通过过冷奥氏体动态相变和随后的等温贝氏体处理,可以获得晶粒细小的铁索体、体积分数较高的残余奥氏体、贝氏体和残余奥氏体分布更加弥散的热轧TRIP钢.
