研究了 20Cr2Ni4A 钢非平衡组织中奥氏体的形成。通过不同温度的等温讨论了针状奥氏体与球状奥氏体的形核和长大特点及其对组织遗传性的影响。
The formation of austenite in non-equilibrium 20Cr2Ni4A steel was studied. The nucleation and growth characteristics of acicular austenite and spherical austenite were discussed by isothermal at different temperatures and their influence on the heredity of the tissue.
