Microstructure and Mechanical Property of an ECAP Processed Al-Mg₂Si In Situ Composite by Using a Combined Route

Abstract:

Microstructure and mechanical property of a hypoeutectic Al-Mg₂Si composite processed by equal channel angular pressing up to eight passes in a combined route 2A+4B_A+2A were investigated. The results show that the initial developed eutectic Mg₂Si was significantly refined into submicrometer-scale particles and distributed homogeneously in the Al matrix, which together with the refinement of Al matrix leads to a much higher ductility with the elongation to failure up to 24% and a significantly enhanced ultimate tensile strength of 284MPa in the processed composite, increased by 2300% and 70%, respectively, compared to those in its as-cast counterpart.
