According to the tempering temperature and hardness curve, the redistribution of residual stress is associated with the transformation of residual austenite.
由回火温度与硬度变化曲线证实，残余应力重新分布是与残余奥氏体转变相关联。

The accurate control temperature by changeable wind method and accurate transformationof transducer will inevitably increase the market proportion of home central air-condition in the future.
A metastable aggregate of ferrite and cementite resulting from the transformationof austenite at temperatures below the pearlite but above the marten site start temperature.
