Summary: The microstructure and texture of binary Mg-0.3Ce alloy were investigated after ECAP processing at 300 and 350 degrees C. Effective grain refinement was achieved through dynamic recrystallization, with different mechanisms observed at different temperatures. Texture development varied based on strain level and DRX mechanisms, forming a typical basal texture at 300 degrees C and a different texture at 350 degrees C due to grain size.

Summary: This study investigates the microstructure and texture evolution of a Mg-3.7Al-0.7Zn-0.8Sn-0.4Mn alloy under different ECAP routes, showing that increasing the number of ECAP passes can improve strength and ductility. The optimized mechanical properties can be achieved through proper ECAP processing, indicating the great potential of Mg-Al-Zn-Sn alloys for low-cost high-strength-ductility wrought Mg alloys.

Summary: This study employed two severe plastic deformation (SPD) techniques, simple shear extrusion (SSE) and equal channel angular pressing (ECAP), to process a magnesium alloy. It was found that the different shear strain paths of the two techniques caused different progression rates of dynamic recrystallization (DRX), resulting in higher recrystallization fractions and high angle grain boundaries (HAGBs) in the ECAP-processed alloy.

Summary: This study investigated the development of an AZ61 hybrid composite (HBC) reinforced with Al2O3 and SiC nanoparticles using the stir casting method and followed by equal channel angular pressing (ECAP). The introduction of reinforcements resulted in the breakdown of precipitates and the enhancement of ductility. The grain size of the HBCs was highly reduced with an increase in the number of ECAP passes. The optimal mechanical properties were observed in the AZ61 + 2%Al2O3 + 1%SiC hybrid composite after two passes of ECAP.

Summary: This study investigates the solution to the problem of internal surface cracking during equal channel angular pressing (ECAP) by modifying a conventional die. The modified die is compared and analyzed with DEFORM-3D software. A modified ECAP die is manufactured to examine the effect of different pressing passes on the microstructure and mechanical properties of the solution-treated Mg93.5Zn2.5Y2.5Mn1Ti0.5 alloy.

Summary: Friction stir welding (FSW) is a commonly used technology for joining low melting point metals or alloys. In this study, large-load and low-speed FSW was used to improve the welding efficiency of an AZ61 Mg alloy, resulting in an ultrafine grain structure and enhanced strength and ductility of the welded joint.

Summary: An Mg-5Sn alloy was processed by ECAP, and the microstructure evolution and mechanical properties were studied. The grain size, amount of Mg2Sn precipitates, and texture varied with the number of passes. ECAP alloys showed improved strengths due to various strengthening mechanisms. The UTS increased while the EL decreased with increasing ECAP pass.
