摘要
发展了新的估算 Cu-Zn-Al 合金热弹性马氏体相变临界驱动力方法。由测量合金的杨氏模量及估算马氏体内的储存能量(层错能),所得的临界驱动力数值与量热法测得热效应后换算的近似值非常接近。
A new approach of estimation of the critical driving force for thethermoelastic martensitic transformation in Cu-Zn-Al alloy is developed.The value of thecritical driving force estimated by measuring the Young′ s modulus of the alloy and find-ing the stored energy (stacking fault energy) in martensite is very close to that derivedapproximately from converting the heat effect measured by calorimetry.
