Investigation of Mechanical, Microstructure Evolution and Corrosion Behaviour of AA7175/TiB2 Composite
Main Article Content
Abstract
This project aimed to create materials with enhanced strength AA7175/TiB2 composites with varying weight fractions of (0-15 %) that were processed via powder metallurgy. The study involved an examination of the powder morphology and structural features of the composites through X-ray diffraction and optical microscope analysis. Additionally, the density, Micro Vickers hardness and tensile properties of the samples were evaluated. Results from the density measurement indicated that enhancing the wt.% of TiB2 particles effectively improved the densification of Al composites. Furthermore, variations in the granularity of Al powder resulted in distinct grain characteristics and the composites exhibited a sharp interface comprising Al/ TiB2. The composite exhibited the highest relative density, hardness and tensile strength at TB15 composite compared to the fabricated composite. The fracture analysis shows both ductile and brittle failure in composite materials. TB15 composite shows a higher corrosion resistance with less pitting region with an increased corrosion duration.
