摘要
对40CrNi和37CrNi3钢组织和断口中出现的奥氏体孪晶进行了观察,对奥氏体孪晶在组织和断口中的形貌进行了分析,得出奥氏体孪晶对冷却时所得马氏体束的方向和奥氏体晶界成分以及断口形貌产生影响。
The austenite twins in the microstructures and fracture surfaces were observed and analyzed in 40CrNi and 37CrNi3 steels. The results show that the austenite twins change the orientation of the lath martensite packets and the compositions of austenite boundaries as well as the morphology of fracture surfaces.
