A commercial ZE41 Mg alloy was processed by equal channel angular pressing (ECAP) using route BC (90o sample rotation after each pass) and route C (180o sample rotation after each pass) at 250, 300 and 350 oC for up to 4 passes. Significant grain refinement from ∼150 μm to ∼33 μm occurred at the higher third and fourth ECAP passes. The most effective process among all routes and temperature combinations was via route C at 250 oC. Nearly 83% increase in yield strength, 58% increase in ultimate tensile strength, and 107% increase in fracture strain were observed after 4 ECAP passes using route C at 250 oC. The increase in the strength of the alloy was attributed to grain refinement during static and dynamic recrystallization. Fractography of tensile samples showed that shallow dimples change to fine dimples at higher passes modifying the failure mode from cleavage to ductile fracture.

“…The plastic deformation of the surface takes place due to the heat generated by the friction between the surface of the workpiece and the shoulder of the tool and also due to the friction between the tool pin and workpiece. V V Kondaiah et al has commented that the heat thus generated will serve the purpose of stirring, and thus the microstructure is modified [17]. In a research work by A Srinivasanaik et al ZE41 magnesium alloy plates were processed with the FSP technique by a tapered high-speed steel tool having shoulder diameter 16 mm [18].…”

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.

“…These two parameters directly influence the amount of heat generated and the material deformation throughout the FSP process [23]. Kondaiah et al [24] found that the rotating speed of the stirring head during FSP of ZE41 Mg alloy had an impact on the degree of refined grains and the breadth of the stirred zone (SZ). Girish and Anandakrishnan [25] found that a high traverse speed above 70 mm/min during FSP of AA7075 Al alloy could lead to insufficient heat input, thus decreasing the plastic deformation of the material.…”

Friction stir processing (FSP) is a solid-state treating method to enhance the mechanical properties of materials by altering their microstructure. In this study, FSP was applied to the AZ91 magnesium alloy cladding layer prepared using cold metal transition (CMT) technology, and the purpose was to investigate the effect of the traverse speed of the H13 steel stirring head under a constant rotation speed on the microstructure and mechanical properties of the cladding layer. The results demonstrated that FSP could effectively decrease the grain size of the cladding layer and lead to the dispersion and dissolution of the coarse β-Mg17Al12 second phase into the α-Mg matrix. The mechanical characteristics of the processed cladding layer were significantly enhanced compared to the unprocessed cladding layer due to the grain refinement and second-phase strengthening induced by FSP. When the stirring head rotation speed was set at 300 r/min, the average microhardness and tensile properties of the specimens showed a tendency of initially increasing and then dropping as the traverse speed increased. The cladding layer, obtained at a traverse speed of 60 mm/min, displayed optimal mechanical properties with an average microhardness, tensile strength, and elongation of 85.6 HV0.1, 278.5 MPa, and 13.4%, respectively.
