Effect of extrusion on the microstructure and mechanical properties of a low-alloyed Mg−2Zn−0.8Sr−0.2Ca matrix composite reinforced by TiC nano-particles
A low-alloyed Mg−2Zn−0.8Sr−0.2Ca matrix composite reinforced by TiC nano-particles was successfully prepared by semi-solid stirring under the assistance of ultrasonic, and then the as-cast composite was hot ex...

The effect of Zn/Ca ratio on the microstructure, texture and mechanical properties of dilute Mg–Zn–Ca–Mn alloys that exhibit superior strength
The microstructure, texture and mechanical properties of a series of Mg–Zn–Ca–Mn alloys with three Zn/Ca ratios (2.63, 1.22 and 0.53, by weight ratio) were investigated. The dominant second phase changed from ...
