Evaluation on Mechanical Properties of Lm14 Reinforced with Paper Sludge Ash

Abstract LM14 alloy reinforced with paper sludge ash is fabricated using stir casting technique and also the effect of paper sludge ash on the composites with various weight percentages (2.5, 3.5, 5) was investigated. From SEM imaging the presence of the reinforcements were observed. EDS analysis confirms the particulates of the reinforcement in the elemental composition. The hardness is increased by 32.3 % from 3.5 wt. % PSA composite and the tensile strength are increased by 42.9% and for 3.5 what% PSA composite when compared to base. Further, addition of reinforcement beyond 3.5 wt. % of PSA with matrix causes reductions in hardness and strength. This effect was due to the non solubility of PSA with matrix. The hot tensile behavior of the composites was observed. The Impact energy of the composites decreased as the content of reinforcement increases. It is observed from the current study, the composites with 3.5 wt% PSA shows better properties.
