变温马氏体相变是重要的相变，其温度场的计算是相变模拟关键环节。
Temperature-floating martensitic transformation is an important transformation during the quenching treatment process. The calculation of temperature field is the key to the transformation simulation.
结果表明，变温马氏体相变及I/C相变过程中内耗均为粘弹性型内耗，是相界面在克服粘滞性阻力而运动时引起的。
The IF behaviour in the processes of MP and I/C phase transformations are nearly the same and is associated with the motion of phase interface under the action of phase transformation driving force.
