通过不同温度亚温淬火及回火,在15~#钢中得到了不同体积百分比及不同强度比的铁素体马氏体双相组织,并从拉伸断口和冲击断口分析研究了这些组织对钢的力学性能及断裂过程的影响。
Through the different temperature sub-temperature quenching and tempering, ferrite martensite duplex structure with different volume percentages and different strength ratios was obtained in 15 ~ # steel. The tensile strength Mechanical properties of steel and the influence of fracture process.
