对改善某些C-Mn钢的强塑性特性进行了研究，结果表明，在650-675°C范围内进行最佳再热处理，可大大改善含Si或不含Si的热轧态0·1C-5 Mn钢的强塑性组合（用抗拉强度×均匀延伸率表示）。由于与加工硬化率的大幅增加有直接联系，因此这种改善很可能是通过再热处理形成的良好稳定的奥氏体的相变诱导塑性的结果。MST/798
As a result of investigations into the improvement of the strength–ductility characteristics of some C–Mn steels, it has been found that the strength–ductility combination (expressed numerically as tensile strength × uniform elongation) of as hot rolled 0·1C–5Mn steels, with or without 2%Si, is greatly improved if an optimum reheating treatment in the range 650–675°C is applied to the steel. Since there is a direct connection with a large increase in the work hardening rate, it is very likely that this improvement is the result of the transformation induced plasticity of well stabilised austenite which has been formed by the reheating treatment.
