Solid-State Phase Transformations and Their Applications in Special Functional Materials

Solid-state phase transformations have been extended from toughening and strengthening of traditional structural materials to advanced functional materials, inducing many interesting physical phenomena. Varieties of functional materials have been developed based on the solid-state phase transformations. Studies on these functional materials have effectively enriches the theories of solid-state materials. The solid-state transformation have become one of the important approaches of functional materials designing and functionalities output. This paper briefly introduces the advances in solidstate phase transformations and their applications in high-temperature shape memory alloys, high damping shape memory alloys, magnetostrictive materials, and thermal barrier coatings.
