| Research Abstract |
The purpose of the present study consists of four folds as listed below.
1) Development of low temperature superelastic Alloy, 2) Medium and high temperature shape memory and superelastic alloy,3)β-Ti and Zr shape memory and superelastic alloys for medical use, 4) New shape memory alloy comparable to Ti-Ni.
In the first purpose, although we have tried to utilize the multistage martensitic transformation (MMT)phenomena to develop the low temperature super elastic alloy, we cannot obtain the sound property. However, we have systematically clarified the effect of parent grain size, alloy composition and heat treatment conditions on the MMT.
In the second purpose, microstructures in Ti-Pd and Ti-Pt alloys which are promising candidates of high temperature shape memory and superelastic materials have been investigated by transmission electron microscopy (TEND).The atomic arrangement of antiphase domain in Ti-Pd alloy and the internal defects of B19 martensite in Ti-Pt alloy have been determined.
High performance β-TiMoSn alloys with various yield stresses have been developed in the third purpose. However, α"martensitic transformation which is origin of shape memory and superelastic properties cannot detected in β-Zr alloys. The trial product of medical guide wire has been made of the developed β-Ti alloy.
In the fourth purpose, new B2 type intermetallic compounds with shape memory effect and high ductility have been developed in Co-Zr-Ni and Co-Zr-Pd ternary systems. However their performance is not comparable to that of TiNi alloys.
