A novel approach in comparison and experimentation of Hybrid Metal Matrix Composites using advanced MCDM methods

摘要

Factual material selection is essential in the manufacturing arena with a superior product and minimum cost.This paper highlights on the advanced multi-criteria approaches namely additive ratio assessment(ARAS)and multi-attributive border approximation area comparison(MABAC)methods for the best material selection of a hybrid composite using aluminum(Al)as base material varying different reinforcement weights and recycling with various industrial wastes by stir casting.Al/WCE gives superior tribomechanical properties at lower cost than the other reinforcements.ARAS and MABAC methods are applied,based on the properties and attributes of the hybrid composites,to compare between the computational and experimental results.The results exactly corroborate with the previous research results which authenticate the expediency of these methods during the solving of complex hybrid material selection problems.Out of 48 different samples,the best hybrid composite material obtained by ranking is material number A30 by ARAS approach(rank 1)which is AI+AI2O3 at 12.5% wt.addition and material number A24(rank 2)which is heat treated 12.5%wt.WCE.But the same A30 is obtained to be rank 5 and A24 is obtained to be rank 1 by MABAC method.A24 is obtained to be the best hybrid composite after the experimentation.
