Abstract
This paper reports on a Ti-50.8 at.% Ni strain glass alloy exhibiting an ultrahigh yield strength (σy = 1.8 GPa) and polymer-like ultralow elastic modulus (E = 10.5 GPa), along with a large elastic strain of approximately 8%. This combination results in a high flexibility figure of merit (σy/E = 0.17). The alloy maintains these properties over a wide temperature range and demonstrates excellent fatigue resistance. Its fabrication involves a scalable three-step thermomechanical treatment, creating a 'dual-seed strain glass' microstructure. The polymer-like deformation behavior stems from a nucleation-free reversible transition between strain glass and martensite phases.
