Influence of Activated Carbon Particles on Microstructure and Thermal Analysis of Aa7075 Metal Matrix Composites

Abstract

The present work represents the AA7075 and Powdered Activated Carbon (PAC) metal matrix composite was processed by down pouring stir casting technique. Invented metal matrix composites were subjected to hardness, tensile test, microstructure analysis, X-ray diffraction, energy dispersive spectrum, FT-IR analysis and thermal analysis. AA7075 metal matrix composites containing matrix and reinforcement. Microstructure suggests the relatively uniform distribution of carbon particles in matrix alloy. X-ray diffraction analysis and EDAX had been making sure the presence of activated carbon particles and its uniform distribution over the aluminium matrix. FTIR trace aging process, the simplest results have been got employing combo of complementary analytical strategies. Hardness and elongation test of AA7075-PAC composite enormously greater in comparison with basic AA7075 alloy and few helpful conclusions have been drawn.

Influence of Microstructural Characteristics on Wear and Corrosion Behaviour of Si3N4-Reinforced Al2219 Composites

“…A composite material is composed of two or more main components with chemical or physical qualities that are quite distinct from one another and that, when combined, produce a material with characteristics that are specifc to each of the constituent parts [1,2]. Several factors, including the new material's superior strength, lighter weight, and more afordable price compared to the old materials, may infuence the decision [3].…”

“…Te main advantage of a composite material over a monolithic metal is the special synthesis of a number of properties that are unusual in traditional materials, improved fatigue resistance, higher stifness-to-weight ratio, and higher strength-to-weight ratio [1,2,[8][9][10]. Improved thermal expansion and corrosion resistance, better optical and magnetic properties, wear resistance, and fracture toughness are only a few of the special combination qualities.…”
