Review of recent developments on metal matrix composites with particulate reinforcement

Abstract

Composite materials are exhibiting such superior properties which cannot be achieved by any monolithic material. At present, the use of metal matrix composites (MMCs) is receiving much attention in the fields of automotive, aerospace, medicine, electronics, etc. Because of the characteristics they have, MMCs can be designed to fulfill all the desired conceptions of the designer. Properties of MMCs are highly influenced by the selection of processing techniques for the fabrication which depends on many factors including type of matrix and reinforcement, the degree of microstructural integrity desired and their mechanical, structural, electrochemical and thermal properties. The aim of this article is to review the current literature and discuss the recent developments and new trends related to fabricating, machining and additive manufacturing of particulate MMCs. The article discusses the various existing and emerging processing techniques for fabricating particulate MMCs. Conventional and nonconventional machining processes, factors that affect machinability, and conventional and nonconventional hybrid machining processes of particulate MMCs, as well as Additive manufacturing techniques that were evolved recently, with additive manufacturing for different metal matrix composites such as aluminum, titanium, etc. are discussed.
