本文建立了一个关于马氏体相变温度和价电子数及电子浓度的经验图谱并设计了一系列ZrCu基形状记忆合金.这些相变温度包括了所有报道过的经Ni、Co、Hf、Ag、Ti、Al、Cr等掺杂替换Zr或者Cu原子的约40种合金.反映了转变温度和电子浓度或者电子密度之间的关系.结果显示ZrCu基合金的转变温度逐渐下降,当cv>0.218时,相变温度急剧下降.ZrCu基合金的马氏体相变温度与电子密度呈线性关系.基于相变温度和滞后图谱的结果可以设计出在不同条件下工作的ZrCu基合金.
In this paper, an empirical map of the martensitic transformation temperatures and valence numbers and electron concentrations has been established and a series of ZrCu-based shape memory alloys have been designed. These phase transition temperatures include all the reported Ni, Co, Hf, Ag , About 40 kinds of alloys such as Ti, Al, Cr doped with Zr or Cu atoms, which reflect the relationship between the transition temperature and the electron concentration or electron density. The results show that the transition temperature of ZrCu-based alloys decreases gradually. When cv> 0.218 , The phase transformation temperature drops sharply.The martensitic transformation temperature and the electron density of ZrCu-based alloy have a linear relationship.The ZrCu-based alloys work under different conditions can be designed based on the results of the phase transition temperature and the hysteresis graph.
