“…This kind of morphology suggests the active role of abrasive wear mechanism for both samples. If the wear test temperature is increased to 125°C, the development of a thin oxide tribo-layer on the Mg surface can be seen particularly when the experiments are conducted in open-air [12]. With the increased temperature, the test material becomes soft and may undergo higher material loss.…”

“…Therefore, understanding the wear mechanisms of Mg alloys at high temperature is essential to develop structures that are subjected to relative motion during application. Chiranth et al [12] reported that the wear rate has been increased for ZE41 Mg alloy (grain size of 72 ± 20 µm) due to the excess formation of oxide layer above 100°C. It is true that smaller grain size influences structure-sensitive properties [7,13].…”

In the current work, ZE41 Mg alloy was processed by friction stir processing (FSP) to achieve grain refinement. In addition to grain refinement, decreased intermetallic phase (MgZn) was also observed after FSP. Increased micro-hardness was observed for the processed ZE41 Mg alloy compared to the unprocessed base alloy. X-ray diffraction (XRD) studies demonstrated the texture characteristics in FSPed ZE41. Reciprocating wear studies conducted at three different temperatures, i.e. room temperature, 125 °C, and 250 °C showed lower mass loss for the processed alloy compared to that of the base alloy, particularly at elevated temperatures. This behavior can be understood by considering the benefit gained from the smaller grains and decreased amount of intermetallic phase in the processed alloy, which reduced the abrasion wear. Hence, the present study suggests that the grain refinement and decreased MgZn phase significantly improve the temperature-dependent tribological characteristics of ZE41 Mg alloy.

“…Wear studies are becoming critical due to unavoidable sliding contact in certain components. However, limited research is only available on wear and friction behaviour of magnesium alloys like AZ31 [32], AZ61, AZ91 [33][34][35], AM60 [36] and ZE41 [37,38]. The wear and friction behaviour are affected by applied load, sliding velocity, and sliding duration and track diameter [39,40].…”

This main purpose of the present research is to investigate the properties of wear and tensile in smooth and notch conditions of the heat-treated Mg-Nd-Gd-Zn alloy. The material applications such as complex helicopter gear box casing, piston and brake actuating components demands tensile data in notch conditions and wear characterizations. The alloy was characterized for microstructure, hardness, tensile properties in smooth and notch conditions and tribological properties such as wear resistance and friction coefficient. The microstructure examination revealed equiaxed grain structure with the size of about 42μm. The XRD results confirms the presence of Mg3 (Nd) precipitates. Smooth and notched samples were evaluated to determine the effect of notch radii and ductile-brittle transition. Notched samples show 25.31% improvements in strength compared to the smooth sample with the marginal reduction in ductility (1.3-1.8%). The fractography results for notched specimens exhibited cleavage, intergranular mode whereas the smooth specimens exhibited quasi cleavage, inter and transgranular modes. At 10N, the wear rate and friction coefficient change from 8.83 x 10-5 mm3/min to 7.11 x 10-5 mm3/min (24.2%) and to 0.29 and 0.26 (11.5%) respectively when the sliding velocity increases from 1 to 5 m/s. Similarly, at 20N, the wear rate and friction coefficient change from 9.11 x 10-5 mm3/min to 0.75 x 10-6 mm3/min (12.7%) and 0.29 to 0.23 (26.1%) respectively when the sliding velocity increases from 1 to 5 m/s. With the increase of load, plastic deformation is dominant controlling the wear rate. With the increase of sliding speed, oxidation is dominant controlling the wear rate and friction coefficient. Mixed modes of wear mechanisms such as abrasion, oxidation, delamination, third body assisted wear and melt wear were observed.

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.
