交互作用能的确定是形状记忆合金热力学本构理论中非常重要且较为复杂的问题.本文基于细观力学的方法和热力学原理,将形状记忆合金复合材料作为三相系统进行分析,即基体相、奥氏体相和生成相马氏体相,推导了形状记忆合金复合材料的交互作用能,该表达式适用于各种形状的夹杂.着重讨论了基体材料、纤维的含量、形状、尺寸和温度等因素对交互作用能的影响.通过比较可知,该方法是可行的,并得到了一些有价值的结论. The determination of the interaction energy is a very important and complex issue in the constitutive theory of thermodynamics of shape memory alloys.Based on the meso-mechanics and thermodynamics principles, the shape memory alloy composite material is analyzed as a three-phase system, ie, the matrix phase, Austenite phase and martensite phase were derived, and the interaction energy of shape memory alloy composite was deduced.The expression is suitable for all kinds of inclusions.Focusing on the matrix material, fiber content, shape, size and temperature And other factors on the interaction energy.The comparison shows that this method is feasible and some valuable conclusions have been obtained.
