摘要对40CrNi2Si2MoVA马氏体钢的奥氏体化行为和力学性能进行了系统的研究。通过扫描电镜和透射电镜测量了奥氏体化温度对合金洛氏硬度和力学性能的影响，并将其与显微组织特征进行了对比。随着马氏体板条的粗化，晶粒尺寸逐渐增大；随着奥氏体化温度的升高，碳化物析出物逐渐溶解。不同奥氏体化温度淬火试样的洛氏硬度值表明，固溶硬化行为变弱。拉伸试验和冲击试验表明，当奥氏体化温度从870℃提高到980℃时，强度下降，冲击韧性明显提高。随着奥氏体化温度的升高，断裂模式由脆性断裂转变为韧性断裂。
Abstract A systematic study on austenitizing behavior and mechanical properties of martensite steel 40CrNi2Si2MoVA has been made in this work. The effect of austenitizing temperature on Rockwell-C hardness and mechanical properties were measured and correlated with the microstructural features measured by scanning electron microscopy and transmission electron microscopy. The grain size grew larger with martensite laths coarsened and the carbide precipitates measured by X-ray diffraction were found to dissolve gradually by raising the austenitizing temperature. Rockwell-C hardness values of samples quenched from different austenitizing temperatures indicated that the solid solution hardening behavior became weaker. Tensile tests and impact tests showed that the strength decreased while the impact toughness improved obviously with increasing the austenitizing temperature from 870 to 980 °C. The fracture mode was changed from brittle fracture to ductile fracture with increasing austenitizing temperature.
