Summary: By accurately controlling the microstructure through ECAP and post-heat treatment, high strength and improved ductility were achieved in an Al-Mg-Li alloy with a high Li content. Refining coarse S-1 phases, uniformly precipitating fine metastable delta' phase particles, and maintaining ultrafine grains resulted in a combination of high strength (>450 MPa) and good ductility (>13.5%). The heat treatment method was also found to be applicable to other Al-Li alloys for adjusting microstructure and achieving an optimal combination of strength and ductility, expanding applications in the aerospace field.

Summary: In this study, a Mg alloy with alloying elements of Zn, Al, Sn, and Mn was designed, and hot extrusion was carried out at various speeds and temperatures. It was found that high speed extrusion resulted in more second phase particles, while high extrusion temperature increased the number of second phases, grain size, and dynamic recrystallization degree. The sample extruded at a speed of 10 mm/min and temperature of 300 degrees C showed the highest yield strength, tensile strength, and corrosion resistance.

Summary: This study investigates the effects of Sn addition on the microstructural characteristics and mechanical properties of an extruded Mg-Bi binary alloy. The results show that the addition of Sn significantly decreases the average grain size and improves the tensile strength and ductility of the alloy. These improvements are attributed to grain refinement, Sn solute atoms, and increased dislocation density.

Summary: Different extrusion conditions can affect the microstructure and mechanical properties of magnesium alloys. Increasing extrusion speed and annealing time can accelerate the growth of recrystallized grains and increase elongation. Large pre-forging deformation can refine the grains and increase the strength of the alloy. Decreasing extrusion ratio or increasing cooling rate will introduce coarse un-DRXed grains and transform the texture. Rapid cooling also has an obvious effect on refining recrystallized grains.

Summary: The evolution of microstructure and mechanical properties of Mg-5.9Zn-1RE-0.6Zr alloy during extrusion and aging processes was studied in this article. The presence of various secondary phases on the matrix was observed during extrusion. The extruded alloy exhibited excellent mechanical properties, with tensile yield strength, ultimate tensile strength, and elongation of 317 MPa, 360 MPa, and 13.9%, respectively. Aging at different temperatures revealed that the alloy with low RE element content is a poor age-hardening MgRE-Zn alloy. The mechanical properties of the alloy aged at 200 degrees C remained relatively stable compared to those aged at higher temperatures, attributed to the stability of the I phases.

Summary: The study found that extrusion temperature and ratio have significant effects on the microstructure, hardness, compression, and corrosion behavior of Mg-5Zn-1.5Y alloy. Lower temperature and higher ratio extrusion conditions provided higher compressive strengths, and the extrusion process decreased the corrosion rate of the alloy in simulated body fluid significantly. Extrusion temperature had a more pronounced effect on corrosion resistance compared to the extrusion ratio, with higher temperatures resulting in higher corrosion resistance.

Summary: This paper investigates the effects of extrusion parameter and quenching cooling rate on precipitation and sensitivity of quench-induced phases in extruded 2196 Al-Li alloy profiles. The results show that a band structure constituted by coarse quench-induced phases and fine aging phases is formed under specific cooling conditions. Increasing the cooling rate reduces the precipitation, size, and density of quench-induced phases, as well as the quenching sensitivity.
