Abstract

This work further investigated the mechanical properties of chemically heterogeneous core-shell austenite. It demonstrated the ability to enhance work hardening capacity and mitigate the formation of the Lüders band. Both experiments and molecular dynamics simulations confirmed that the Mn chemical boundary acts as a barrier to martensitic transformation during deformation.
