Selected shape memory alloys are synthesized using electrochemical deposition. Three alloy systems are selected for the initial research, In-Ti, In-Cd, and In-Pb. The structure and shape memory transformation behavior are compared to conventionally-processed alloys. Layered shape memory Fe-Ni alloys are to be produced in a modulated, nanolayer form using pulse plating. Characterization methods include X-ray diffraction, internal stress measurement, scanning and transmission electron microscopy, and Auger spectroscopy. %%% Electrolysis offers potentially valuable synthesis capability, which has been improved with recent advances in technology. Direct deposition in the form of thin films or multilayer configurations can be used to produce unique materials.

使用电化学沉积合成选定的形状记忆合金。 初步研究选择了三种合金体系：In-Ti、In-Cd 和 In-Pb。 将结构和形状记忆转变行为与传统加工的合金进行比较。 层状形状记忆铁镍合金将使用脉冲电镀以调制的纳米层形式生产。 表征方法包括 X 射线衍射、内应力测量、扫描和透射电子显微镜以及俄歇能谱。 %%% 电解提供了潜在的有价值的合成能力，随着最新技术的进步，这种能力得到了改进。 薄膜或多层结构形式的直接沉积可用于生产独特的材料。
