根据损伤力学原理建立了材料单轴抗拉一抗压本构模型，并应用有限元软件对其进行了数值拟合，通过实验曲线、本构模型曲线之间的关系，证明了理论推导方法的可行性。
According to the phenomenon of friction interface transferring , two techniques of processing ultra - fine grain material were advanced to develop new method of preparing large bulk of ultra - fine grain material efficiently and economically . the first is the friction interface thermo - induced transfer method ( fitt ) for column part , and the second is the cooling friction stir processing ( cfsp ) for flat part
为探索一种高效率、低成本制备大块超细晶结构材料的新方法，本文按照摩擦压扭强变形区连续转移的总体思路，提出了两种具体的制备工艺： ( 1 )适用于棒材的摩擦面热诱导转移法， ( 2 )适用于板材的强冷搅拌摩擦工艺。
