The phase transformation thermodynamics of post-transition metals, which form low-melting-point alloys, remain largely unknown. This project aims to explore low-energy metallurgy pathways enabled by liquid metals to discover such dynamics. The strategy is to harvest structured/crystalline materials by incorporating target metal species into liquid metal solvents and stimulating autonomous phase separation and pattern formation during phase transition. Contemporary instruments and technologies will be employed to achieve active control of these fundamental processes at different scales. The expected outcomes will reveal new insights in traditional metallurgy as well as extend metallurgical concepts to electronics, optics, and catalysis.Read moreRead less
