摘　　要：通过固定其它元素的含量,调整碳含量的方式,研究了碳含量对马氏体钢显微组织和力学性能的影响。结果表明,随碳含量增加,马氏体钢的硬度和抗拉强度提高,但冲击韧度下降。The influence of carbon on microstructure and mechanical property of low-carbon martensite steel was studied by fixing the content of other elements and regulating the content of carbon. The results show with increasing the content of carbon, the hardness and tensile strength of low-carbon martensite steel enhenees, but the impact strength falls down.

关 键 词：马氏体钢 硬度 冲击韧度
