刚度可调先进材料已在多个领域展示了其优越性和多功能性，而全球对刚度调节的可逆、智能和快速响应的追求正在急剧增长，这给传统材料带来了巨大挑战。作为新兴的功能金属材料，低熔点合金（LMPAs）由于其优异的物理化学和机械性能，在开发各种刚度调节策略方面显示出令人鼓舞的潜力。本文致力于从材料体系、调控原理与方法、能力使能机制、应用场景等方面对LMPA使能的刚度可调材料进行全面综述。首先，根据结构差异，评估了三种启用 LMPA 的刚度可调材料系统。然后，从基本的LMPA修改到动态外场控制，阐述了调节策略，并梳理了主流的刚度调节模式。随后，系统总结和讨论了LMPA使能刚度可调材料的多样化应用。最后，提供了对启用 LMPA 的刚度可调材料的潜力和挑战的透视解释。本文有望对指导未来智能材料、功能实体、可变形机器人等的设计具有重要意义。并对主流的刚度调节方式进行了梳理。随后，系统总结和讨论了LMPA使能刚度可调材料的多样化应用。最后，提供了对启用 LMPA 的刚度可调材料的潜力和挑战的透视解释。本文有望对指导未来智能材料、功能实体、可变形机器人等的设计具有重要意义。并对主流的刚度调节方式进行了梳理。随后，系统总结和讨论了LMPA使能刚度可调材料的多样化应用。最后，提供了对启用 LMPA 的刚度可调材料的潜力和挑战的透视解释。本文有望对指导未来智能材料、功能实体、可变形机器人等的设计具有重要意义。

Low Melting Point Alloys Enabled Stiffness Tunable Advanced Materials

Stiffness tunable advanced materials have demonstrated their superiority and versatility in diverse areas, while the global pursuit of reversible, intelligent, and fast response for stiffness regulation is growing radically, leaving great challenges for traditional materials. As newly emerging functional metal material, the low melting point alloys (LMPAs) have shown encouraging potential in developing various stiffness regulation strategies owing to their excellent physicochemical and mechanical properties. This article is dedicated to presenting a comprehensive review of the LMPA-enabled stiffness tunable materials from the aspects of material system, regulation principle and method, capability enabling mechanisms, and application scenarios. First, according to the structural differences, three kinds of LMPA-enabled stiffness tunable material systems are evaluated. Then, the regulation strategies are elaborated from the fundamental LMPA modifications to dynamical external field controls, and the mainstream stiffness regulation modes are also combed out. Following that, the diversified applications of LMPA enabled stiffness tunable materials are systematically summarized and discussed. Finally, a perspective interpretation of the potentials and challenges of LMPA-enabled stiffness tunable materials is provided. This article is expected to be important for guiding the future design of smart materials, functional entities, transformable robots, etc.
