In this research work an attempt was made to reinforce AA7075 composites with B4C and SiC particles through stir casting route. SEM with EDS mapping revealed that the reinforcement were uniformly over the composites and hardness reduces with the addition of SiC particles owing to the inverse hall petch effect. The results revealed that wear rate reduces with addition of SiC particles owing to the formation of mechanically mixed layer and protective oxide layer confirmed through SEM with EDAX mapping. Three distinct cracks were formed, when slides at different temperature as confirmed through worn surface morphology, pits cracks and plasticization of material were the other features observed. The used motor oil properties were analyzed and results divulged that the oil suitable for dielectric fluid. Increase in Material Removal Rate (MRR), reduction in Tool Wear Ratio (TWR) and Surface Roughness (Ra) was observed with the incorporation of powder particles owing to the bridging effect. Black spots, craters, micro pits, globules and micro crack are the distinct observed on the machined surface topography. The modified Preference Ranking Organization METHod for Enrichment of Evaluations (PROMETHEE) optimization technique was utilized to find the optimal parametric combination.

“…The interfaces between a metallic glass and a crystalline metal (alloy) are crucial not only in particle- or ribbon-reinforced composites but also in welds [ 96 , 97 , 98 , 99 ] and sintered layered structures [ 50 ]. In a broader context, metallic glass–crystalline metal interactions are special cases of interactions between multi-component alloys and metals, which play a key role in the structure formation of metallic alloy particle-reinforced composites [ 100 , 101 ]. Therefore, studies of the chemical interaction and diffusion between metallic materials of different crystalline structure and composition are of fundamental importance for many systems.…”

When metals are modified by second-phase particles or fibers, metal matrix composites (MMCs) are formed. In general, for a given metallic matrix, reinforcements differing in their chemical nature and particle size/morphology can be suitable while providing different levels of strengthening. This article focuses on MMCs reinforced with metallic glasses and amorphous alloys, which are considered as alternatives to ceramic reinforcements. Early works on metallic glass (amorphous alloy)-reinforced MMCs were conducted in 1982–2005. In the following years, a large number of composites have been obtained and tested. Metallic glass (amorphous alloy)-reinforced MMCs have been obtained with matrices of Al and its alloys, Mg and its alloys, Ti alloys, W, Cu and its alloys, Ni, and Fe. Research has been extended to new compositions, new design approaches and fabrication methods, the chemical interaction of the metallic glass with the metal matrix, the influence of the reaction products on the properties of the composites, strengthening mechanisms, and the functional properties of the composites. These aspects are covered in the present review. Problems to be tackled in future research on metallic glass (amorphous alloy)-reinforced MMCs are also identified.

“…Magnesium (Mg) is the most crucial candidate among the different materials due to its low density and high specific strength [4]. Mg alloys have many advantages, such as high stiffness, good damping ability, superior biocompatibility, recyclability, machinability and huge hydrogen storage capacity [5][6][7][8]. Nevertheless, the widespread use of Mg alloys is limited due to their poor formability, low corrosion resistance and poor wear properties [9][10][11][12].…”

The demand for magnesium (Mg) alloys is increasing in many industries, such as automotive and aerospace, thanks to their low density and high specific strength. However, the poor tribological performance of Mg alloys is one of the most important disadvantages that limit their widespread use. Researchers have developed different approaches to improve the wear performance of Mg alloys, such as alloying, coatings, surface modifications and composite production. Wear performance of systems with sliding parts are crucial for a lifetime and energy efficiency. The development of Mg matrix composites can significantly reduce energy loss by reducing damage from friction and wear. For this reason, it is crucial to understand the wear behaviour of recent Mg matrix composites. The effect of different parameters such as load, sliding speed, reinforcement content, reinforcement type and temperature on the wear performance of Mg matrix composites were investigated.
