Microstructural characterization and mechanical behavior of Al-4 wt% Mg2Si in-situ metal matrix composite synthesis via cooling slope casting technique

Microstructure Control and Performance Evolution of Hypereutectic Al–20Mg2Si Alloy by Novel Al–Ca–Sb Masteralloy

“…At present, a variety of methods have been studied to improve the microstructure organization of metallic alloys including chemical modifiers, [ 8 ] mechanical methods, [ 9,10 ] and heat treatment. [ 11 ] Yadav et al [ 12 ] used the cooling slope casting technique to cast A319–4 wt%Mg 2 Si composites and found that Mg 2 Si particles were remarkably refined and uniformly dispersed in the matrix, which contributed to the improvement of mechanical properties including hardness and tensile strength. Moazami et al [ 13 ] studied the microstructure and mechanical properties of Al–15Mg 2 Si– x TiB 2 composites in the as‐cast and wrought conditions and found that the fragmentation, dispersion, and spheroidization of pseudo‐eutectic Mg 2 Si constituents resulted in a significant enhancement of tensile properties due to the hot deformation by extrusion process and elevated temperature exposure.…”
