Mg-3Al-1Zn alloy deformed along different strain paths: Role of latent hardening

open access: yesJournal of Magnesium and Alloys, 2023
The mechanical properties of magnesium alloy AZ31 were investigated experimentally with visco-plastic self-consistent modeling. Tension, compression and plane strain compression (PSC) tests were performed along 3 directions of a hot rolled plate, and the

Influence of thermomechanical processing on microstructure, mechanical and strain hardening properties of single-phase Mg-4Li-0.5Ca alloy for structural application

open access: yesJournal of Magnesium and Alloys, 2020
The single-phase Mg- 4Li- 0.5Ca alloy was rolled at three different temperatures (250, 300 and 350 °C) and followed by annealing at 200 °C for 10 min. To evaluate the mechanical properties, the tensile test was conducted at a constant strain rate of 10−3

Dislocation multi-junctions and strain hardening [PDF]

open access: yesNature, 2006
At the microscopic scale, the strength of a crystal derives from the motion, multiplication and interaction of distinctive line defects called dislocations. First proposed theoretically in 1934 (refs 1-3) to explain low magnitudes of crystal strength observed experimentally, the existence of dislocations was confirmed two decades later.

Orientation Influence on Tensile Strain Hardening in Forged Plates of AA2014 Aluminium Alloy [PDF]

open access: yesArchives of Metallurgy and Materials
Strain hardening is an effective strengthening method for alloys that requires plastic deformation of the material during manufacturing. The strength will significantly increase due to the number of dislocations formed during plastic flow of material ...
