The title of project is “Mechanical properties of metal at the micrometer scale in different environment.” This project will focus on the ductile-to-brittle transition of body-centered-cubic materials at the micrometer scale. We believe that the size effect strongly influences the ductile-to-brittle transition. We will use in-situ cryogenic micromechanical testing, advanced transmission electron microscopy, and dislocation dynamics simulation to elucidate the fundamental dislocation processes at low temperatures (30~300K). The research outcome will be useful to develop a mechanically reliable structure at small length scales, which operates in cryogenic environments such as the deep space.
