Preparation of AL-7075 B4C & Graphite Composite using Powder Metallurgy Technique

Abstract

In the present world, people knock themselves out for the fabrication of hybrid composites to know the mechanical behaviour by choosing Al 7075 hybrid composites. By adopting frequent additional reinforcement which is graphite 3% and varying the other reinforcementB4C in the same aluminium matrix. The composites like Al-B4C-Gr were fabricated. FESEM was conducted on all the fabricated composites to know the uniformly dispersed of the backup in the aluminium template.  From every composition, the scores are taken to know them better. In the end, the hardness points a non-hybrid and hybrid composite which are compared.
