用室温透射Mossbauer谱研究了不同条件下淬火处理对钢中马氏体基体组织、残留奥氏体量和其含碳量的影响规律,阐明了高温直接淬火和形变淬火处理提高强韧性的效果与残留奥氏体量无明显关系。
The effects of quenching treatment on martensite matrix, retained austenite content and carbon content in steel under different conditions were investigated by transmission Mossbauer spectroscopy at room temperature. The effects of direct quenching and deformation quenching at high temperature on the strength and toughness were discussed. No significant relationship between the amount of retained austenite.
