The influence of carbon on microstructure and mechanical property of low-carbonmartensite steel was studied by fixing the content of other elements and regulating the content of carbon.
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。

Observations showed that the micro-structure of the steel after forging or high temperature rolling was composed of low-carbonmartensite, a little part of bainite and residual austenite.
The formation of the inter-lath austenite in quenched low-carbon steels is described and the existence of the carbon diffusion during the lath martensite formation is emphasized.
