Effect of reinforcement of AL-6063 with SiC on mechanical behavior and microstructure of metal matrix composites
Journal Title: Carbon - Science and Technology - Year 2014, Vol 6, Issue 2
Abstract
A phrase heard often in recent years, advanced composite materials like Al/SiC metal matrix composite is gradually becoming very important materials in auto and aerospace industries due to their superior properties. The present study examines the mechanical properties of aluminum (Al-6063)/SiC Silicon carbide reinforced particles metal-matrix composites (MMCs) by varying weight fractions of SiC. For this (Al-6063)/SiC reinforced particles MMCs are fabricated by stir casting method at air atmosphere. The MMCs are prepared in the form of bars with varying the reinforced particles by weight fraction ranging from 2 %, 4 %, 6 %, 8 % and 10 %. The reinforced particles size of SiC is varying between 25 - 40 microns. The microstructure study shows that the distribution of particles becomes better with increasing weight fraction of SiC. The Mechanical properties like, Ultimate tensile strength (MPa), % Elongation, Hardness (HRB), Yield Strength (N.m) are investigated on prepared specimens of MMCs. It was observed that the hardness of the composite is increased gradually from 2 - 6 % and drastically from 8 – 10 %. The tensile strength and ultimate break load are increased with rising of reinforced weight fraction and the improvement varies between 15.8 - 27 % and 2 - 15 % respectively.
