Cu—Zn—Al合金具有形状记忆效应、超弹性和高阻尼本领,其潜在用途与特征性能的某些参量例如正。反马氏体转变温度、在M_3以上给定温度感生马氏体所需的应力以及在任一温度的阻尼本领等的稳定性和“预马氏体转变”相关。因此在形状记忆合金的研究中时效效应问题一直受到重视,而预马氏体转变作为一个新颖的研究领域正引起人们极大的兴趣。
Cu-Zn-Al alloys have shape memory effect, superelasticity and high damping ability, and their potential applications and some parameters such as characteristic performance are positive. The inverse martensitic transformation temperature, the stress required to induce martensite at a given temperature above M_3, and the damping ability at any temperature, etc., are related to the “pre-martensitic transformation.” Therefore, the problem of aging effect has been paid more attention in the research of shape memory alloy, and the pre-martensite transformation is attracting great interest as a new field of research.
