应力-温度-相变（STT）图和变形-温度-相变（DTT）图适用于表征钢中的TRIP（相变诱导塑性）和TTRIP（孪生诱导塑性）效应。变形诱导微观结构转变过程的触发应力、特征温度、屈服应力和钢的强度作为温度的函数绘制在STT图中。奥氏体、应变诱发孪晶和马氏体形成的延伸率值显示在DTT图上。
Stress‐Temperature‐Transformation (STT) and Deformation‐Temperature‐Transformation (DTT) diagrams are suitable to characterize the TRIP (transformation‐induced plasticity) and TWIP (twinning‐induced plasticity) effect in steels. The triggering stresses for the deformation‐induced microstructure transformation processes, the characteristic temperatures, the yield stress and the strength of the steel are plotted in the STT diagram as functions of temperature. The elongation values of the austenite, the strain‐induced twins and martensite formations are shown on the DTT diagram.
