Aluminium Matrix Composites (AA6061/CaSiO₃) Obtained by Powder Metallurgy

Abstract

Aluminum matrix composite materials (AMCs) are widely used in components for the aerospace and automotive industries [1]. These compounds show a high strength/weight ratio, good mechanical properties and greater durability due to the addition of particles as reinforcements [1,2]. The present work will focus on the study of the reinforcement of AA 6061 alloy with particles of CaSiO3 (wollastonite). Powder metallurgy is widely used to control the dispersion of particles in AMCs [3,4]. The present work aims to study the influence of different contents of CaSiO3 on the microstructure of the alloy matrix and the effect of the powder metallurgy technique by optical microscopy (OM), scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM / EDS).
