New in-situ composite materials with aluminium alloy matrix (6063) and vanadium boride particles

Abstract

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.
