Microstructure Study of Aluminium Matrix Hybrid Composite Materials

Abstract

This study aims to produce aluminium matrix hybrid composite materials using Powder Metallurgy (PM) techniques and to investigate the microstructural properties of the resulting materials in detail. In the initial phase, various powder mixtures were processed using powder metallurgy and cold pressing methods, followed by sintering to complete the production of the composite materials. After their production, comprehensive examinations were conducted to analyze the microstructural characteristics of the composites. These investigations focused on the aluminium matrix reinforcement phases' distribution, size, morphology, and interfacial properties between the matrix and reinforcements. During this analysis, modern techniques such as Optical Microscopy (OM), Scanning Electron Microscopy (SEM), and X-ray Diffraction (XRD) were employed to perform in-depth microscopic and structural assessments of the samples.
