Independent dislocation space model for synchronous improvement of strength and plasticity in fcc metals

doi:10.1016/j.jmst.2024.12.002

Abstract

Abstract: In this study, the possible relationships between strength and plasticity are explored on the basis of the stability and mobility of dislocations. An independent dislocation space (IDS) model is proposed by molecular simulation of pilling-up and annihilation behaviors of screw dislocations in face-centered cubic (fcc) metals. It is revealed that there is an intrinsic driving mechanism for the restrictive strength-plasticity relation, and then the criterion for the synchronous improvement of strength and plasticity (SISP) in dislocation mechanism dominated fcc metals is proposed in terms of the IDS model. Finally, the IDS model has been verified in various practical cases and could help design high-performance metallic materials in future.

Key words: Dislocation behavior, Strength, Plasticity, Fcc metal
