Microstructure and interface characterization of a cast Mg2B2O5 whisker reinforced AZ91D magnesium alloy composite

Light Metal Matrix Composites

“…Microstructure and interface studies of Mg 2 B 2 O 5 whisker reinforced AZ91D composite by Chen et al (2010) showed that the Mg 2 B 2 O 5 whiskers have a twinned structure with the (2 0 2) as the twin plane and growth direction along [0 1 0] and that MgB 4 O 7 particles and globular Mg 2 Si particles were observed within the Mg 2 B 2 O 5 whisker, and Mg 2 B 2 O 5 whiskers/Mg-matrix interface. Further, MgO and MgB 2 phase formed at the matrix-whisker interface during vacuum-gas pressure infiltration process due to the interfacial reaction (Fig.…”

Effect of hot extrusion on microstructures and mechanical properties of SiC nanoparticles reinforced magnesium matrix composite

“…In order to improve the mechanical properties of Mg, significant efforts have been taken to develop magnesium matrix composites (MMCs) due to their low density and superior specific properties including strength, stiffness and creep resistance [1][2][3][4][5][6][7][8]. Compared with the unreinforced magnesium alloys, tensile strength and elastic modulus of the micro particles reinforced MMCs are normally improved, but their ductility is reduced, which limits their widespread application.…”

Interfacial and fracture behavior of short-fibers reinforced AE44 based magnesium matrix composites

“…The magnesium matrix composites (MgMMCs) can offer potential applications in most severe conditions of automobile power-train to attain the maximum lighten effect, only if they can be approved to own similar overall properties to compete Al-MMCs, with which have already been used in cylinder bores and pistons for decades [7][8][9]. However, comparing with aluminum-based MMCs, few efforts have been made to study the magnesium-based MMCs [10].…”
