摘　　要：采用计算机模拟软件研究了Fe-0.6C、Fe-0.6C-1Cr和Fe-0.6C-1Mn合金的奥氏体化过程。结果表明,合金奥氏体转化过程受C或微量元素扩散的影响。通过计算珠光体组织完全转化成奥氏体的时间,发现片层珠光体的奥氏体转化过程极快。The austenitizing processes of the alloy Fe-0.6C、Fe-0.6C-1Cr and Fe-0.6C-1Mn were investigated by computer-simulation sottware. The results show that the austenitizing process of the alloy is affected by the diffusion of C and trace element. It is found by calculating the completed austenitizing time from pearlite, that the austenitizing process of laminar pearlite is extremely fast.
