本文根据76个成分点的试验结果及文献[1]中的有关结论,建立了含有不同稳定性大小奥氏体区的较为完整的Fe-Mn-C系合金1000℃固溶处理后的组织图,并对各类锰钢的化学成分范围及组织变化规律进行了分析与讨论。工业用锰钢的成分和组织可依据该组织图进行合理选择。
Based on the test results of 76 component points and the relevant conclusions in reference [1], the histogram of the more complete Fe-Mn-C alloy containing different sizes of austenite with different stability at 1000 ℃ after solution treatment was established , And analyzed and discussed the chemical composition range and microstructure variation of various types of manganese steel. The composition and organization of industrial manganese steel can be rationally selected according to the organizational chart.
