Mechanical properties of Al(Mg) solid solution prepared by solidification under high pressures
2012
Abstract Mechanical properties of Al(Mg) solid solution with different Mg solubility prepared by solidification under high pressure were investigated in the present study. The results show that the tensile strength of solid solution increases first, and then decreases with increasing Mg solubility. Fractographic examination reveals that the fracture characteristic transforms from dimple-like fracture to combination of quasi-cleavage plus intergranular fracture with increasing Mg solubility. This trend is believed not only limited to Al(Mg) solid solution, but also to other solute-strengthened alloys.
