Aluminium Metal Matrix Composites Fabricated by Powder Metallurgy Techniques: A Review

Nowaday’s composite materials are at top in material selection process because of its superior mechanical, chemical and corrosive properties. But, predicting the behaviour of composites with different reinforcements and their content levels is complex because of different fabrication techniques give different properties. To use reinforcements up to its fullest in a metal matrix, suitable processing techniques have to be select so that composite with good interface bond strength and better mechanical properties can be obtained. Interface bond strength plays a major role in robustness of the composite material. Interface bond strength depends on many factors like type of reinforcement, sintering temperature, intermetallic compounds formed, etc. In this paper, a very good review is presented about composites with different reinforcements and their content levels, processing techniques, sintering temperatures, strengthening mechanisms along with theoretical equations and robustness of the composites obtained by each and every technique is included for comparison purpose.
