Abstract
This current research work is primarily focused on comparative experimental study on effect of two distinct fabrication process routes i.e. liquid state and solid state process and their corresponding parameters on microstructure and micro-hardness properties of Aluminium matrix composites (AMCs). In this work, AMCs were fabricated by reinforcing Al2O3 powder materials of 5, 10 and 15 wt.% into pure Aluminum (Al) matrix phase through two distinct processes; liquid state (stir casting) and solid state (powder metallurgy) process. In case of liquid state process, small pieces of pure Al ingots were melt into a bottom pouring type stir casting furnace followed by adding of preheated reinforcements and continued stirring till homogeneous mixing of reinforcement. In case of solid state process, 5, 10 and 15 wt.% Al2O3 powder materials were mixed with pure Al by following planetary ball milling concept followed by hot competing at 1500 psi and sintering at 500, 600 and 700oC for two hours. Microstructures were observed under an inverted optical microscope. Micro-hardness were measured by micro Vickers hardness testers. It is observed that equixed type grain structures are formed in case of AMCs fabricated through liquid state processing confirming that specimens were fabricated through casting process; however non-equaxed type grain structures are formed in case of AMCs fabricated through powder metallurgy process. It is interestingly observed that hardness of AMCs is more in case of specimens fabricated through liquid state process as compared to specimens fabricated through solid state process irrespective of addition of wt.% reinforcement; however, the hardness increases with increase in wt.% reinforcement for both the cases.
