摘要: 冲击载荷作用下，相变波的传播及相互作用是一热力耦合过程。采用理论和实验相结合的方法研究了固定温度界面对相变波传播特性的影响。首先基于形状记忆本构模型和一维特征线理论分析了各类间断面和温度界面的基本相互作用规律，发现温度界面对相变波的作用与相变波强度及界面两侧温度的相对高低有关；然后进行了相变波在具有固定温度界面的形状记忆TiNi杆中的传播实验，并实时测量了相变波传播过程中的温度变化。实验结果与理论分析基本一致，冲击载荷作用下相变波不仅是物质间断面，还是移动的温度界面。Abstract: The propagation and interaction of the phase transformation waves is a thermal-mechanical coupling process under shock loading.In this research, we investigated the effect of a fixed temperature interface on the phase transition propagating by theoretical analysis combining with experiment.First, on the basis of the shape memory constitutive model and the one-dimensional characteristic line theory, we analyzed the basic law of interactions between kinds of cross sections and the temperature interface.The results reveal that the property of the interaction is associated with the strength of phase transition wave and the relative size of temperature on two sides of the temperature interface.Then, we carried out the experiment of the phase transition wave propagating in a shape memory TiNi bar with a temperature interface, the results of which is consistent with the theory analysis; and we in situ measured the change of temperature in the process of the phase transformation propagation, showing that the phase transition wave is not only the material cross section, but also the moving temperature interface under shock loading.
