“…[1][2][3]. Many characters, such as: a high ratio of strength to density, high ratio of stiffness to density, and excellent surface properties, combined with a reasonable cost, make these alloys commercially very attractive [4][5]. As distinguished representatives, Mg-Al-Zn and Mg-Al-Mn alloys are given to an attractive attention.…”

“…Some researches have been done on 10 μm SiCp reinforced magnesium matrix composites, and these researches revealed that the introduction of 10 μm SiCp led to a significant improvement of fracture, yield strength and ultimate strength [4] . These investigations on the SiCp reinforced magnesium matrix composites confirm that the size, content and the shape of particles have a great influence on the mechanical properties of magnesium alloys [9][10][11] . However, until now few results have been reported in the literatures on magnesium matrix composite reinforced by 1 μm SiC particles, especially fabricated by a semisolid stirring assisted ultrasonic vibration method [12][13][14] .…”

Mg-Zn-Ca-Mn matrix composites reinforced with two volume fractions (1 and 3 vol%) of SiC particles (1 μm) were fabricated by a semisolid stirring assisted ultrasonic vibration method, and then extruded at 350 °C with the extrusion ratio of 15:1. The microstructures of the composites were examined by optical microscopy (OM), scanning electron microscope (SEM) and transmission electron microscopy (TEM). The microstructure analysis shows that the relatively uniform SiCp distribution and the refined grains are obtained in the 1 vol% SiCp/Mg-Zn-Ca-Mn and 3 vol% SiCp/Mg-Zn-Ca-Mn composites after the extrusion. The introduction of SiCp can improve yield strength and ultimate tensile strength. Both of the yield strength and ultimate tensile strength increase with the increase of SiCp content.

“…[12][13][14] Owing to the non-uniformly distributed stored energy, the Mg alloys often undergo partially dynamic recrystallisation, and thus, inhomogeneous microstructure of the Mg alloys is often observed under only once extrusion, which apparently deteriorates the elongation. 12,15 Fine and homogeneous microstructure can be easily obtained through some severe deformation methods, such as repeated plastic working, 16 double extrusion, 17 equal channel angular pressing, 18 cyclic extrusion and compression, 19 high pressure torsion process 20 and cyclic closed die forging.…”

In order to refine and homogenise microstructure and to improve mechanical properties of the magnesium alloys for biomedical application, the Mg-2.0Nd-0.1Zn-0.4Zr (wt-%, NZ20K) alloy with low amount of alloying elements was processed by double extrusion and aging processes (DEAP). Compared to the NZ20K alloy after once extrusion and aging processes (OEAP), the microstructure becomes finer and more homogeneous, and the elongation is raised up ∼121% by DEAP. Moreover, the yield strength and ultimate tensile strength are improved ∼27 and ∼16% respectively. Additionally, the corrosion rate of the NZ20K alloy by the DEAP is a little slower than that of the OEAP. It can be concluded that the mechanical properties, as well as the corrosion resistance of the NZ20K alloy, are able to be enhanced by the double extrusion and aging processes.
