Strain hardening recovery mediated by coherent precipitates in lightweight steel [PDF]
Scientific Reports, 2021 We investigated the effect of κ-carbide precipitates on the strain hardening behavior of aged Fe–Mn-Al-C alloys by microstructure analysis. The κ-carbides-strengthened Fe–Mn-Al-C alloys exhibited a superior strength-ductility balance enabled by the ...

Strain Hardening at Large Strains [PDF]
, 1989 The strain hardening properties of various fcc metals have been investigated at large strains by means of torsion tests of short thin-walled cylinders. The results show that Stage IV occurs in all cases provided that a low enough test temperature is used; it is a nearly constant hardening rate of 2.10/sup /minus/4/ G in terms of resolved flow stress ...

Evaluation on Flexibility of Phenomenological Hardening Law for Automotive Sheet Metals
Metals, 2022 Constitutive modeling of sheet metals involves building a system of equations governing the material behavior under multi-axial stress states. In general, these equations require a hardening law that describes the stress-strain relationship.
