Experimental and computational investigation on mechanical properties of aluminium alloy 6063/waste eggshell powder metal matrix composite

Abstract 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.
