Experimental and computational investigation on mechanical properties of aluminium alloy 6063/waste eggshell powder metal matrix compositeExperimentelle und rechnerische Untersuchung der mechanischen Eigenschaften von Metallmatrix-Verbundwerkstoffen aus Aluminiumlegierung 6063/Abfall-Eierschalenpulver

In the present investigation, food industries ' waste eggshell is used to fabricate the metal matrix composite i. e., made by stir casting method. Further, two different composition samples have been prepared, with a mixing of 6 weight-% eggshell and 12 weight-% eggshell carbonized powder in matrix material aluminium alloy 6063. Sample B (aluminium alloy 6063+6 weight-% eggshell) and sample C (aluminium alloy 6063+12 weight-% eggshell) in the aluminium alloy 6063 powder (sample A) are mixed with the help of the mechanical stir casting method. The final test results revealed that hardness increased by 16.73 % and 27.57 % value for sample B and sample C respectively than aluminium alloy 6063 (sample A). In addition, the tensile strength and impact hardness of sample B and sample C also increased by 17 % to 31 % value respectively in comparison to aluminium alloy 6063 (sample A). In the last power law, hardening parameters have been evaluated for sample B for performing the finite element analysis of the tensile test process. The finite element analysis model has shown good agreement with experimental results. In the present investigation, a metal matrix composite has been fabricated with aluminium alloy 6063 and carbonized eggshell powder (with 150 mu m particle size) by stir casting method with a considerable amount. Results revealed that properties like hardness, impact strength and tensile strength increase with increasing weight percent of reinforcement material into aluminium alloy 6063.image
