Abstract

Abstract

En 中文
• In RHES, dislocation motion faces unprecedented resistance from APBs and severe lattice distortion. • Microcracks preferentially nucleate and rapidly propagate along {100} planes in BCC phase, causing catastrophic fracture. • Dislocation motion hindered, preventing strain-hardening zone at crack tip, thus fails to suppress cleavage fracture.
