Ultra-fine-grained and gradient FeCrAl alloys with outstanding work hardening capability

, 2021
FeCrAl alloy is a promising accident tolerant fuel cladding material for next generation nuclear reactors. Grain refinement may lead to FeCrAl alloys with improved mechanical properties. However, the addition of Al retains the ferrite phase and makes the

Multistage work hardening assisted by multi-type twinning in ultrafine-grained heterostructural eutectic high-entropy alloys

, 2020
High strength of materials usually comes with low ductility due to the lost or short-lived strain hardening. Here, we uncover a sequentially-activated multistage strain hardening (SMSH) that allows for sustained and effective strain-hardening capability ...

Some aspects on geometric and matrix work-hardening characteristics of sintered cold forged copper alloy preforms [PDF]

Materials Research, 2013
Powder metallurgy (P/M) material subjected to plastic deformation results into densification, however the extended deformation would not only enhance the densification also supplements the strain hardening.

Phenomenological Modeling of Deformation-Induced Anisotropic Hardening Behaviors: A Review

Metals, 2023
Numerous studies indicate that the hardening behaviors of materials are closely related to their deformation history. In the forming processes with loading path changes, such as sheet metal forming, anisotropic hardening behaviors are universally ...
