摘要

Abstract

Reversibility of phase transformation

a basic requirement for functional properties of shape memory alloys

such as superelasticity

is severely affected by plastic deformation. Here

strain glass has been utilized to improve the reversibility of phase transformation. The incorporation of Al into Ti-Zr-Ni-Cu induces strain glass and endows the alloy with reversible phase transformation and thus ideal superelasticity.

In situ

x-ray diffraction and dynamic mechanical experiments were utilized to verify the mechanism for the conversion from transformation plasticity to superelasticity. This work provides a new way to improve the reversibility of phase transformation and expands the practical implications of strain glass.
