“…As the lightest metal structural material available in nature, magnesium alloy had attracted much more attention in the field of aerospace, automobile, electronic communication, etc [1][2][3][4]. However, the low modulus, low wear resistance, high coefficient of thermal expansion and poor high-temperature performance of magnesium alloy limit its application in industrial engineering.…”

Particle reinforced magnesium matrix composite (PMMC) possesses the merits of high specific strength, high specific modulus, better dimensional stability, good wear resistance and lower production cost, which is thought as a promising material in the field of aerospace, automobile, electronic communication, etc. To eliminate the casting defect, the PMMC is usually experienced hot deformation process. The present paper mainly focuses on the deformation behavior of PMMCs. First, the development of PMMCs based on particle size is introduced. Then, the hot deformation technology and deformation mechanism of PMMCs at elevated temperature are given and analyzed, respectively. After reviewing the dynamic recrystallization and texture of PMMCs, its future development is suggested based on the current research progress.

“…Magnesium alloy is the lightest metal structural material, with many advantages such as high specific strength, high specific elastic, excellent damping performance, good dimensional stability, strong electromagnetic shielding capacity, abundant resources and recyclable reuse. However, its poor corrosion resistance and room temperature ductility greatly limits its widespread application [1][2][3][4][5] . By comparison, as is well-known that aluminum alloys have some advantages such as high specific strength, good plastic and strong corrosion resistance.…”

Low-temperature severe plastic deformation of pure magnesium

In this paper, the microstructure and texture of pure magnesium after rolling at low temperatures have been investigated. Pre-deformed magnesium in the form of a plate with the thickness of 1 mm was rolled at room and cryogenic temperatures down to foils with 150 µm thickness. The true strain was ε ~1.9. Methods of X-ray diffraction, scanning electron microscopy with electron backscattering diffraction analyses (EBSD-analysis) and transmission electron microscopy have been used to investigate the structure and texture of the magnesium foils. In the initial state, the plate has a weakened basal texture and fine-grained structure. It was shown that the basal texture (0001) became stronger during rolling regardless of the deformation temperature. In all cases, the structure was heterogenic and consisted of large recrystallized grains with preferred basal orientation and smaller (sub)grains. However, it was noted that the room-temperature rolling led to an increase of the fraction of large grains, and lower deformation temperature prevents an active grain growth. The change of the number fraction of low-angle and high-angle boundaries could point on different lead mechanisms during deformation. At room-temperature rolling, there is the predominance of slip processes and dynamic recrystallization. As for at cryo-deformation, the twinning is more active and the dislocation slip could be suppressed for a while.
