Abstract

In this paper, we investigate the characteristics of Ti-Ni-Zr thin film metallic glasses (TFMGs)/ shape memory alloys (SMAs) for microelectromechanical systems (MEMS) applications with three-dimensional structures. The amorphous Ti-Ni-Zr thin films having a Ni content of more than 50 at.% and Zr content of more than 11 at.% undergo glass transitions and are TFMGs. The Ti₃₉Ni₅₀Zr₁₁ TFMG has the lowest glass transition temperature T_g of 703 K and a wide supercooled liquid region ΔT of 57 K. Moreover, it has high thermal stability at T_g. However, the apparent viscosity of the Ti₃₉Ni₅₀Zr₁₁ is higher than those of other Ti-Ni-Zr TFMGs. Moreover, the Ti-Ni-Zr TFMG exhibits higher viscosity than conventional TFMGs because the alloy composition of Ti-Ni-Zr TFMGs/SMAs is far from the eutectic point.
