Abstract

Vanadium boride (VB)particulate reinforced Al-7 wt.% Si based metal matrix composites (MMC) were synthesized using mechanical alloying (MA) and pressureless sintering. (Al-7 wt. % Si)-2 wt.% VB blends were mechanically alloyed for 4h in a high energy ball mill. Particle size measurement, Brunauer-Emmett-Teller (BET) surface area analysis, scanning electron microscopy (SEM) investigation and thermal analysis were conducted to characterize the mechanically alloyed powders. As-blended and mechanically alloyed powders were compacted in anuniaxial hydraulicpress with a pressure of 450 MPa and green compacts were sintered at 570°C under Ar gas flowing conditions. Microstructural and phase characterizations of the sintered samples were carried out using optical microscope (OM), SEM and X-ray diffractometer (XRD). Physical and mechanical properties of the sintered composites were investigated in terms of density measurements, microhardness measurements and wear rate. MA enhances the physical and mechanical properties of the composites. (Al-7 wt.% Si)-2wt.% VB MA'd for 4 h had relative density value of 95.55%, microhardness value of 1.04±0.11 GPa and wear rate of 1.42×10^-5 mm₃/mm.
