Development of Aluminium Matrix Composites: A review

Aluminium matrix composites (AMCs) are a range of advanced engineering materials that can be used for a wide range of applications within the aerospace, automotive, biotechnology, electronic and sporting goods industries. AMCs consist of a non-metallic reinforcement (SiC, B4C, Si3N4, AlN, TiC, TiB2, TiO2) incorporated into Aluminium matrix which provides advantageous properties over base metal (Al) alloys. These include improved abrasion resistance, creep resistance, dimensional stability, exceptionally good stiffness-to-weight and strength-to-weight ratios and better high temperature performance. Fabrication of these advanced engineering materials through liquid state and solid state routes are considered in this paper
