The Effect of Precipitation hardening Heat Treatment on Impact Toughness and Tensile Properties of AA6063 Aluminum Alloy Reinforced with Hybrid Particles from Al2O3 and Graphite

Abstract

Aluminum based composite are getting a vast scope nowadays because of its high properties and availability as fit large industrial development. (AMC) Aluminum metal-matrix composites is new engineering materials which contains two or more materials with different properties one being a metal from Aluminum and other may be metal, ceramic , glass  reinforced materials.  So in This  present article We try to prepare hybrid composite materials based on aluminum alloy (AA6063) and reinforcement it by shared particles having size of micron of Alumina (7.5 wt%)  and Graphite particles are added in specific countrified parentage  (2.5 , 5 , 7.5 , 10 wt%)  by stir casting technique to obtain hybrid Aluminum  Which having  the improving mechanical properties  ,Heat treatment (solution heat treatment-artificial aging) are carried out on all samples ,After that inspections and mechanical tests have be done  on all reinforcement samples , The results of Scanning electron microscope have shown uniform distribution of hybrid reinforced particles in matrix alloy and hybrid reinforced Aluminum alloy successfully prepared using stir casting method. The results of tests have shown  The Impact toughness, , and Ultimate tensile strength  were determined, with the addition of  reinforcement the properties and effect of Precipitation hardening Heat treatment are improved compared to the parent metal Aluminum (6063) alone.
