【摘要】 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。更多还原

【Abstract】 The martensite microstructure, amount of retained austenite and itscarbon content in 40CrNiMo steel quenched at various conditions have been in-vestigated by using transmission Mossbauer spectroscopy at room temperature. It wasshown that the toughening effect of high-temperature quenching and the thermome-chanical quenching has little correlation with the amount of retained austenite.更多还原
