摘要

The magnesium AZ61 series is used as the matrix phase of the proposed composite fabrication, with the additions of 3 wt.% of titanium (Ti) and then 2–6 wt.% of boron nitride (BN) particles by the vacuum-aided stir casting production method. During the AZ61 alloy’s melt processing, argon gas is used as a cover atmosphere to minimize oxidation. The vacuum die-cast processing and combined Ti/BN actions on surface morphology, porosity, measured density, impact toughness, tensile performance, and hardness of AZ61 alloy composites are examined. Surface morphology revealed even dispersion of Ti and BN particles in the AZ61 alloy surface. The accumulation of Ti/BN particles on the AZ61 alloy matrix is visible as a significant enrichment in impact toughness, tensile performance, and hardness value. Validation of 2 X 105 Pa vacuum pressure: the porosity of the AZ91 alloy composite is recorded by a downtrend with hiked content of BN. However, the accumulation of 3 wt.% Ti/6 wt.% BN in the AZ61 matrix offered 1.82 g/cm3 of measured density, 22.67 ± 0.2 J/mm2 of impact toughness, 185 ± 4 MPa of yield strength, 310.2 ± 6 MPa of tensile stress, and 88 ± 1 HV of microhardness.
