抄録

<p>In this paper, we proposed the combinatorial evaluation method of thermal properties such as glass transition temperature Tg and crystallization temperature Tx for Ti-Ni-X high formable shape memory alloys (HFSMAs). We fabricated the integrated library consisting of 5 samples with different alloy compositions. This library was prepared by carousel type co-sputtering system using metal shadow masks. Alloy composition distribution of this library had homogeneous in one direction (RD direction). In contrast, in another direction (TD direction), this library had compositionally graded alloy composition. Finally, we combinatorial-evaluated thermal properties of 5 Ti-Ni-Zr amorphous samples on the library. 3 samples showed glass transition, and they were thin film metallic glasses. Specifically, they were HFSMAs. Other 2 samples did not show glass transition, and they were only amorphous sample (only SMAs). These results agreed with the results of previous paper using conventional sequential evaluation methods.</p>
