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

Dislocation multi-junctions and strain hardening [PDF]
Nature, 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]
Archives of Metallurgy and MaterialsStrain 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 ...
