图9. 不同经验公式下奥氏体的堆垛层错能(γSF)、30%应变条件下50%奥氏体转变为马氏体的温度(Md30)与低周疲劳寿命Pearson相关性系数(ρXY)的关系
Fig.9. Relationships between ρXY of low cycle fatigue life and γSF and Md30 of austenite under different empirical equations distinguished by subscripts a~d (ρXY—Pearson correlation coefficient, γSF—stacking fault energy, Md30—temperature of 50% austenite transformed to martensite under 30% strain)
