摘要
对G-X12CrMoWVNbN10-1-1耐热铸钢进行正火和回火热处理后,观察其微观组织;奥氏体化后采用风冷和油冷,研究淬火冷却速率对其微观组织和力学性能的影响;正火后采用不同温度回火,研究回火温度对微观组织和力学性能的影响。
After normalizing and tempering heat treatment for G-X12CrMoWVNbN10-1-1 heat-resistant cast steel, observe the microstructure of the steel on casting, normaling and tempering state respectively; cooled in air and oil after austenitic, research the effect of quenching rate on the microstructure and mechanical properties; tempering in different high temperature after normaling; research the effect of tempering temperature on microstructure and mechanical properties.
