    • Devices and methods of making devices having one or more components made of single crystal shape memory alloy capable of large recoverable distortions, defined herein as “hyperelastic” SMA. Recoverable Strains are as large as 9 percent, and in special circumstances as large as 22 percent. Hyperelastic SMAs exhibit no creep or gradual change during repeated cycling because there are no crystal boundaries. Hyperelastic properties are inherent in the single crystal as formed: no cold work or special heat treatment is necessary. Alloy components are Cu—Al—X where X may be Ni, Fe, Co, Mn. Single crystals are pulled from melt as in the Stepanov method and quenched by rapid cooling to prevent selective precipitation of individual elemental components. Conventional methods of finishing are used: milling, turning, electro-discharge machining, abrasion. Fields of application include aerospace, military, automotive, medical devices, microelectronics, and consumer products.
    • 制造具有由具有大的可恢复失真的单晶形状记忆合金制成的一个或多个部件的装置的装置和方法,在本文定义为“超弹性”SMA。 可回收的菌株高达9%,在特殊情况下高达22%。 超弹性SMA在重复循环过程中没有表现出蠕变或逐渐变化,因为没有晶界。 超弹性性质在形成的单晶中是固有的:不需要冷作或特殊的热处理。 合金成分是Cu-Al-X,其中X可以是Ni,Fe,Co,Mn。 单晶从熔融中拉伸,如Stepanov方法,并通过快速冷却淬火,以防止各种元素组分的选择性沉淀。 使用常规的精加工方法:铣削,车削,放电加工,磨损。 应用领域包括航空航天,军事,汽车,医疗器械,微电子和消费品。
