The presence of complex states-of-stress and strain-rates directly influence the dominant deformation mechanisms operating in a given material under load. Mg alloys have shown limited ambient temperature formability due to the paucity of active slip-

Mg alloys are among the lightest alloys but they are usually weak. Here we report a new mechanism to make them ultrastrong while maintaining good ductility. Stacking faults with nanoscale spacing were introduced into a Mg–8.5Gd–2.3Y–1.8Ag–0.4

This work examines the influence of microcracking on a material’s tendency to shear localize under compressive loading. A two-dimensional (2D) finite-element framework with explicit crack representation using cohesive-element methodologies is emplo

Notably the most dominant twinning mode in hexagonal close-packed metals, {1012} twinning presents abnormal properties such as reversible twinning and non-Schmid effect. The twin boundaries may significantly deviate from the {1012} twinning plane. HC

Poor deformation behavior of tantalum (Ta) sheet used for tin diffusion barriers in Nb3Sn composite superconductors can lead to Ta layer rupture and even strand fracture during wire drawing. These problems arise because the Ta layer deforms nonunifor

Large grained pure niobium was processed by multi‐pass equal channel angular extrusion and then annealed with the objective of producing a fine‐grained uniform recrystallized microstructure. Extrusions were performed on 25 mm square cross‐secti
