The plastic deformation of polycrystalline metals is primarily carried by the crystallographic glide of dislocations and growth of deformation twins. According to the thermodynamic …
In this work, quantitative crystallographic and microstructural analyses of γ, γ′, γ ″, δ, and MC carbide phases are performed on wrought samples, samples fabricated via additive …
This work adapts a recently developed multi-level constitutive model for polycrystalline metals that deform by a combination of elasticity, crystallographic slip, and deformation …
In this work, a hybrid metal matrix composite with WE43 magnesium alloy as matrix and a hybrid mixture of NiTi, iron, and tin as reinforcement was fabricated using friction stir …

This paper examines deformation behavior of WE43 alloy in direct-chill as-cast (as-cast- WE43) and rolled heat-treated T6 (WE43-T6) conditions with an emphasis on fracture …
A number of studies have found that the formation of double twins in low symmetry metals can lead to the onset of strain localizations, leading further to void nucleation and ultimately …
