Abstract In recent years examples of unprecedented functional and structural fatigue resistance and lowered hysteresis in shape memory alloys have been achieved by combining conditions of supercompatibility between phases with suitable grain size and a favorable array of fine precipitates. We collect, review and compare these examples to elucidate the relative roles of these factors, especially in the case of the more demanding stress-induced phase transformations, and we pose key open questions. The control of these factors lends itself to systematic alloy development. Taken together, these results point to significant opportunities to discover improved shape memory alloys as well has new reversible transforming multiferroics.

形状记忆合金的相工程和超相容性

摘要 近年来，通过结合具有合适晶粒尺寸的相之间的超相容性条件和一系列有利的细小析出物，已经实现了前所未有的功能和结构抗疲劳性以及形状记忆合金滞后降低的例子。我们收集、审查和比较这些示例以阐明这些因素的相对作用，特别是在要求更高的应力引起的相变的情况下，我们提出了关键的开放性问题。这些因素的控制有助于系统的合金开发。总之，这些结果表明发现改进的形状记忆合金以及具有新的可逆转变多铁性的重要机会。
