Crystalline-amorphous architectures modulate martensitic transformation and mechanical response in NiTi

Abstract NiTi shape memory alloys (SMAs) exhibit outstanding pseudoelasticity, yet the strongly first-order nature of their martensitic transformations (MTs) produces autocatalytic strain avalanches and large hysteresis that limit controllability and energy efficiency. Recent exp...

A superelastic titanium alloy showing nearly temperature-independent high strength and elastic modulus

Lightweight superelastic alloys with temperature-insensitive properties are critical for deep-space exploration devices, yet their development is hindered by the challenge of simultaneously balancing strength, recoverable strain, and temperature sensitivity. Here, we overcome the...
