The scaling behavior of Ti–Ni–Cu shape memory thin-film micro- and nanowires of different geometry is investigated with respect to its influence on the martensitic transformation properties. Two processes for the high-throughput fabrication of Ti–Ni–Cu micro- to nanoscale thin film wire libraries and the subsequent investigation of the transformation properties are reported. The libraries are fabricated with compositional and geometrical (wire width) variations to investigate the influence of these parameters on the transformation properties. Interesting behaviors were observed: Phase transformation temperatures change in the range from 1 to 72 °C (austenite finish, (A_f), 13 to 66 °C (martensite start, M_s) and the thermal hysteresis from −3.5 to 20 K. It is shown that a vanishing hysteresis can be achieved for special combinations of sample geometry and composition.

用于高通量缩放效应的形状记忆微型和纳米线库

就其对马氏体相变特性的影响，研究了不同几何形状的Ti-Ni-Cu形状记忆薄膜微细线和纳米线的缩放行为。报道了高通量制备Ti-Ni-Cu微纳薄膜薄膜线库的两种工艺，以及随后对转变性能的研究。这些库是根据成分和几何（线宽）变化制作的，以研究这些参数对变换特性的影响。观察到有趣的行为：相变温度在1到72°C（奥氏体完成度（A _f），13到66°C（马氏体开始，M _{s）范围内变化}）和-3.5至20 K的热滞。表明，对于特殊的样品几何形状和成分组合，可以实现消失的磁滞。
