Development and influence of tribomechanical properties on magnesium based hybrid metal matrix composites-a review

Abstract

Composite materials are being widely studied for the last few decades, and it has optimized the day to day applications in the engineering field. In this advancement, the use and development of metal matrices was a significant outcome that concentrated on the addition of many particulate materials in a metal matrix at nano and micro levels. Among these Magnesium, metal matrices are having a high potential, especially in transport, defense, and aircraft industries. Many research works are being carried out to use the capabilities of Magnesium and has provided excellent results. This paper is an overview of the development, processing, and improvement of properties in Magnesium alloys. Various manufacturing processes such as self-propagating high-temperature method, stir casting, laser cladding, and powder metallurgy has been used to develop the magnesium composites for increasing the properties by using various wt% of reinforcements added in the matrix. The improvement in mechanical properties such as tensile strength, yield strength, hardness and tribological properties such as wear rate is reviewed. The different properties and capabilities of Magnesium alloys such as AZ31, AZ91, and ZE41 is also discussed from the various research works.
