“…The grain size of a material is the average diameter of the reinforcement particles in the matrix which can be characterized by microstructure evaluation through scanning electron microscopy and x-ray diffraction spectroscopy. Grain Size of the RZ5 Mg matrix reinforced with TiC at 10 weight% has decreased from 250 to 20 μm, and hence the hardness of the matrix was increased [15]. The grain size of the ZE41 Mg alloy is found to have decreased from 110 μm to 7 μm when reinforced with calcium, and hence the hardness of the composite material is found to have increased [19].…”

“…Diffusion and convection of melted metal and nonmetal takes place after this and it will create the nucleation of reliable products and crystal growth takes place. D Mehra et al in their work, has reinforced a magnesium RZ5 alloy with Titanium carbide (TiC) by the Selfpropagating high-temperature method [15]. RZ5 Magnesium alloy was heated at about 750°C with argon shielding in a graphite container.…”

“…Hardness of a material is the resistance against abrasion or indentation and is normally measured by using Brinnel, Vickers or Rockwell hardness testing machines.In a research work by D Mehra et al magnesium alloy RZ5 was reinforced with Titanium carbide(TiC) having 10 wt% contribution [15]. The outcome of this research showed that the hardness of RZ-5 reinforced with 10% TiC has increased considerably compared to the RZ-5 alloy without reinforcement which was prepared by self-propagating high-temperature method.…”

“…The tensile strength of a material is the maximum amount of tensile stress a material can withstand before failure, which can be experimentally found out by using a universal testing machine. The tensile strength of TiC reinforced RZ5 Mg alloy has increased from 179 to 195 MPa [15]. This is because the TiC will act as load bearers in the composite.…”

“…The yield strength of a material is a critical design parameter which represents the initiation of plastic deformation which can be plotted from the stress-strain diagram of a material. The yield strength of the RZ5 Mg matrix reinforced with TiC at 10 weight% has reduced from 140 to 121 MPa [15]. The presence of microcavities and particle cracking has increased the yield strength of the SiC reinforced composite to 90 MPa from 68MPa [2].…”

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.

A new severe plastic deformation for manufacturing Al/Mg bimetallic tube called TES (Tube Extrusion Shearing) process, which combines direct extrusion with two step shearing, is developed to Al/Mg bimetallic tube. To explore the deformation mechanism for Al/Mg bimetallic tube during TES process, both experiments and numerical simulations have been carried out. The stroke loads during TES process of Al/Mg bimetallic tubes have been simulated by establishing three-dimensional nite element model. Experiments show that by use of TES process the microstructures can be re ned to 50% of the original grain size and with more uniform grain distribution. TES process could improve hardness obviously by comparing which fabricated by direct extrusion. Numerical results indicate TES increases the cumulative strains effectively by direct extrusion and additional shearing. The micro-structures and mechanical properties of the bonded layer were analyzed, The results showed that under the extrusion temperature of 420℃, the bonding layer of the sample obtained by extrusion shearing had no hole defects, and the thickness was about 22um, among which the stable layer was about 11um.The average hardness of the bonding layer is 221HV.
