The exothermic reactions between AA 6063 alloy, AlV master alloy, and inorganic salt mixture (KBF4) result in the fabrication of matrix alloy 6063 reinforced by in-situ obtained VB2 particles via liquid metallurgy. The presence of VB2 was revealed using optical microscopy and by the XRD patterns. The reinforcing particles act as a grain refiner at 1% concentration of VB2. A set of compressive tests were taken to showcase the compressive stress-strain curves of the different samples at different concentrations of VB2.
