| Outline of Final Research Achievements |
The purpose of this study are to establish new 3D printing method for shape memory alloy using viscous flow of Ti-Ni-based thin film metallic glasses (TFMGs) / shape memory alloys (SMAs) in supercooled liquid region. Ti-Ni-based TFMGs show glass transition, and crystallized Ti-Ni-based TFMGs show shape memory effect.At first, we investigated the viscosity of Ti-Ni-Zr and Ti-Ni-Cu TFMGs. Both TFMGs show the viscosity order of 1010 Pa・s.
We tried to prepare the Ti-Ni-based MG powder by a gas atomizing or mechanical alloying. However, we couldn’t prepare them. In further work, we prepare the MG ribbon by melt spun method, and we will establish new 3D printing method for SMA using them.
