Experimental investigation and optimization of powder metallurgy processing parameters of Si3N4/HfC/MoS2 reinforced with Al 7075

This present investigation is to enhance the hardness and tensile behavior of secondary particles reinforced with Al 7075. The secondary particles considered for this study are Si3N4 (2 wt%, 5 wt% and 8 wt%), HfC (0.5 wt%, 1.25 wt% and 2 wt%) and MoS2 (2 wt%, 3.5 wt% and 5 wt%). The hybrid metal matrix composites are fabricated using powder metallurgy technique. The fabricated samples were analyzed using scanning electron microscope and the presences of elements are confirmed by using energy dispersive spectroscopy. The two main mechanical properties are considered in this study such as tensile strength and hardness. Response surface methodology optimization technique is adopted to find the effective powder metallurgy process parameters and secondary particle optimal values to enhance the mechanical property. Analysis of variances results reveals that compacting pressure were the maximum influencing parameter for both the hardness and tensile strength.
