Improving the mechanical properties of BN reinforced magnesium composites using vacuum sintering method

Abstract

Magnesium matrix composites with BN particles at 2%, 4%, and 6% weight percentages were developed via powder metallurgy. These composites for maritime usage were created. For compacting 15 min were spent maintaining 250 megapascals at 2500 degrees Celsius. Further, this material is sintered for eight hours at 6500 degrees Celsius. The morphology of a synthetic magnesium composite was assessed using SEM. It was observed that the absence of clustering in the matrix alloy reinforcing particles allowed lamellar precipitates to develop during diffusion on the composites. With stronger and stiffer matrix alloy reinforcement, the compressive strength (23%) and hardness (18%)of magnesium composites are increased. This improvement strengthens the intermixture. Magnesium composite corrosion was evaluated in the B117 salt spray test. With reinforcement, corrosion in magnesium composites becomes better (18%) when Alpha magnesium solid solution decreases as reinforcing expands.
