Heterostructured materials as a new class of materials have excellent mechanical properties due to hetero-deformation induced (HDI) strengthening and hardening. However, how do heterostructural parameters affect the evolution of geometrically necessary dislocations (GNDs) and HDI stress remains...

Microstructure, texture and mechanical properties of extruded Mg- x Gd sheets (x =1.0, 1.5, 2.0 and 2.5 wt%) were discussed, and microstructural evolution of an Mg-1.0Gd alloy during extrusion were investigated. The extrudedMg- x Gd sheets presented a fully recrystallized microstructure. The...

While Magnesium (Mg) matrix composites have been intensively investigated as the promising light structural materials, the relatively low ductile nature limited their wide-scale applications. Herein, we report that AZ91 Mg matrix composites reinforced by Ti-6-Al-4V (TC4) particles were prepared...

For basal textured magnesium alloy subjecting to in-plane compression, the deformation is complicated since twinning, dislocation slipping and their intersecting are involved. In this work, a high-resolution digital image correlation (HR-DIC) technique combined with electron backscatter...
