This book provides a clear detail about the usage of aluminium matrix composites for different engineering applications. It deliberates about the effects of reinforcement on the Aluminium matrix composites. Aluminium matrix composites of various percentages were produced by powder metallurgy technique. The objective of this study is to investigate the influence of reinforcement on the matrix material subjected to mechanical properties such as hardness and tensile strength after hot extrusion process. The author's aim of this book is to provide wide-ranging exposure of production of aluminium matrix composites via powder metallurgy technique. This book contains 52 pages, 38 figures and 4 tables.
