Theoretical Simulation-Guided Design of Wide-Temperature and Large-Recoveriable Shape Memory Alloys:Research Progress
China's future space exploration plans focus on a series of deep-space missions,including exploration of the Moon's regions shadowed permanently,sample return missions from asteroids and Mars,exploration of the Jupiter system and in-terstellar traversal,as well as exploration at the edge of the solar system.These ambitious exploratory activities aim to expand China's capabilities in deep-space exploration,achieve significant scientific breakthroughs,and substantially enhance the country's space technology.The increasing complexity of deep-space missions demands high-performance materials capable of en-during wide temperature ranges and significant deformation,especially those exhibiting super-elastic behavior.This article pro-vides an overview of researches conducted over the past decade on the interaction mechanisms between point defects and martensi-tic phase transformation dynamics,as well as their impact on the behavior of wide-temperature-range super-elastic materials.It attaches particular emphasis on the significant role played by computational simulation techniques in understanding the dynamics of nucleation and growth of martensitic phase transition at the microscale.Leveraging computational simulation tools in conjunc-tion with the growing power of artificial intelligence not only aids in a deeper understanding of the mechanisms behind changes in material properties,but also drives the design of new materials,thereby providing stronger support for China's deep-space explo-ration endeavors.
