摘要

Abstract

BSTRACTHigh-temperature shape memory alloys (HTSMAs) show enormous potential for applications as energy conversion devices

actuators and sensors in automotive

aerospace

and energy exploration industries

but they suffer from strength decrease and microstructural instability at elevated temperatures

rendering it difficult to achieve satisfactory high-temperature superelasticity. Here

a novel Ti

high-entropy HTSMA exhibiting large superelasticity with a fully recoverable strain of 4.0% at temperatures up to 285°C is designed with the high-entropy alloy concept by employing the sluggish diffusion and severe lattice distortion effects to suppress thermal softening. This work illuminates the design of novel high-performance functional materials for high-temperature applications.
