Atomic faulting induced exceptional cryogenic strain hardening in gradient cell–structured alloy

Science, 2023
Coarse-grained materials are widely accepted to display the highest strain hardening and the best tensile ductility. We experimentally report an attractive strain hardening rate throughout the deformation stage at 77 kelvin in a stable single-phase alloy

The hardening soil model: Formulation and verification

Beyond 2000 in Computational Geotechnics, 2019
A new constitutive model is introduced which is formulated in the framework of classical theory of plasticity. In the model the total strains are calculated using a stress-dependent stiffness, different for both virgin loading and un-/reloading.

Hetero-deformation induced (HDI) hardening does not increase linearly with strain gradient

Scripta Materialia, 2020
Hetero-deformation induced (HDI) hardening has been attributed to geometrically necessary dislocations (GNDs) that are needed to accommodate strain gradient near the interfaces of heterostructured domains.

Abnormal TRIP effect on the work hardening behavior of a quenching and partitioning steel at high strain rate

, 2020
Quenching and partitioning (Q&P) steels possess high strength and good ductility because of the transformation of metastable austenite to martensite, which is referred to transformation-induced plasticity (TRIP) effect.

Structures and formation mechanisms of dislocation-induced precipitates in relation to the age-hardening responses of Al-Mg-Si alloys

, 2020
In the slightly deformed Al-Mg-Si alloys, dislocation-induced precipitates are frequently observed, and they usually line up, forming sophisticated precipitation microstructures.
