Synopsis

Superplasticity is the capability to deform crystalline solids in tension to unusually large plastic strains. It is an important property for the forming and shaping of materials. Superplasticity is usually achieved at high temperature, typically half the absolute melting point. Recently, a group of Ti alloys, named Gum Metals, demonstrate surprisingly superplastic-like cold workability at room temperature. This project aims to apply ex situ and in situ straining transmission electron microscopy to explore the mechanisms behind this peculiar phenomenon. The project will be of great importance for the fundamental study and for guiding future materials design for superior mechanical properties.
