with a wheel speed of 52 m/s. The uniformity of grain size in heat treated ribbons decreases with increasing wheel speed. Key words: Ti-Ni; melt-spun ribbon; microstructure; shape memory alloy 1 Introduction It has been known that Ti-Ni thin films show shape memory effects comparable to those of bulk materials. The Ti-Ni shape memory alloy (SMA) thin films are expected to be utilized for various......
