冷速对过冷奥氏体稳定性的影响

Influence of Cooling Rate on Sub-Cooled Austenite Stability

分别测定了冷速对奥氏体稳定性不同的五种钢种先共析铁素体、珠光体、贝氏体等温转变孕育期以及TTT曲线的影响,并对所得结果给出理论解释。

Five steel grades of different austenite stability have been studied. The effect of cooling rate on incubation period of isothermal transformation into proeutectoid ferrite, pearlite and bainite were measured. The influence of cooling rate on TTT Curves was studied too. And a theoretical explanation has been given.
