| 摘 要： | 利用一种特殊的机械热处理工艺技术,即在控轧终轧后经过一段控制时间与温度的弛豫,使得基体中出现应变诱导析出以及变形奥氏体中缺陷组态重组,在随后的直接淬火或加速冷却过程中,获得细化的板条贝氏体/马氏体组织.利用该弛豫-析出-控制相变(RPC)技术能得到屈服强度大于800 MPa级12mm厚超细贝氏体/马氏体复合组织微合金钢板.

| Abstract: | By a special thermomechanical control process(TMCP-RPC), relaxation for a certain time after control rolling and then direct quenching/accelerated cooling, the strain induced precipitions and defect structure in deformed austenite resulted in refinement of intermediate transformation microstructure. Following this relaxation-precipitation-control phase transformation (RPC) process,800 MPa grade plate steel with an ultra-fine mixture microstmcture of bainite and martensite was obtained. The effect of processing parameters on the microstructure and the mechanical properties was revealed. |
