“…When the temperature over 498 K, the ductility of Mg alloy increases greatly with the temperature due to the behaviors of recovery and recrystallization. 14) Thus above this temperature, Mg alloys can be plastically deformed smoothly, such as rolling 15) and extruding. 16) In the case of extruded Mg alloys, many researches focus on equal channel angular extrusion (ECAE).…”

We report microstructure evolution and mechanical properties of Mg alloy AZ31 processed by a new severe plastic deformation technique which combines forward extrusion, equal channel angular extrusion (ECAE) and change channel angular extrusion (CCAE). Under all of the processing temperatures ranging from 623 K to 723 K, the grain size of the as-extruded sample was remarkably refined, which is attributed to the grain subdivision and dynamic recrystallization during the drastic deformation. We have also found the strength and tension-compression asymmetry were improved. Simultaneously, micro-fracture of tensile exhibited the characteristics of ductility, indicating plasticity of Mg alloy AZ31 was improved by compound channel extrusion.

“…In particular conditions where only a small amount of material is available, the small specimen testing methods such as shear punch testing technique (SPT) are considered to reduce the costs and difficulties of the standard tensile specimen preparation [7,8]. Hence, SPT is a promising method to resolve the situations where conventional mechanical testing techniques are practically not possible such as weld joints [9], coatings, failed components, very small volumes of irradiated materials [10], biomaterials, composites and metallic glass [11].…”

An AZ31magneium alloy was processed through accumulative back extrusion (ABE) process at 280 °C up to six passes. Compressive deformation behavior of the processed materials was studied by employing uniaxial compression tests at room temperature. The results indicated that grains of 80 nm to 1 µm size were formed during accumulative back extrusion, where the mean grain size of the experimental material was reduced by applying successive ABE passes. A deformation texture characterizing with the basal plane mainly lie inclined to the deformation axis was developed. Compressive yield and maximum compressive strengths were measured to increase by applying successive extrusion passes, while the strain-to-fracture dropped. The evolution of mechanical properties was explained relying on the grain refinement effect as well as texture change. It was described that the share of different deformation mechanisms and developing of shearing regions near the grain boundaries may influence the deformation behavior of the ultrafine/nano grained AZ31 alloy.
