“…10 The poor wettability of copper with ceramic particles and improved wettability with metals have led researchers to develop a hybrid metal matrix, which has enhanced mechanical properties along with corrosion resistance and wear resistance. Several studies [11][12][13][14][15][16][17] have reported that hybrid composites comprising copper þ highly strained stainless steel (HSSS) þ tungsten carbide (WC), manufactured through the stir-casting process, exhibit high hardness and tensile strength. Stainless steel is converted into HSSS after the grinding process.…”

The present study involved development of copper-based metal matrix composite, reinforced with waste EN 31 steel chips and TiB2 ceramic particles. Waste EN 31 steel chips and TiB2 ceramic particles were ball-milled for 100 h to obtain a single entity. The composite material was produced with a stir-casting technique, followed by a squeeze pressure process. The addition of Cu + 10 wt% of waste steel chips + 5 wt% of TiB2 improved the tensile strength of the copper matrix by about 68.35%. Furthermore, the addition of Cu + 5 wt% of waste steel chips + 10 wt% of TiB2 and Cu + 12.5 wt% of waste steel chips + 2.5 wt% of TiB2 increased the hardness and toughness of the copper matrix by about 133.33% and 28.57%, respectively. The addition of Cu + 10 wt% waste steel chips + 5 wt% of TiB2 ensured minimal corrosion weight loss in the metal matrix composite as a result of low porosity and a strong bond between the molecules. Further, representative volume element (size: 225 × 225 × 225 nm)-based finite element analysis was done to explain the micro-mechanical deformation, interfacial strength of matrix-particle interaction and damage behavior of Cu + 10 wt% of waste steel chips + 5 wt% of TiB2 metal matrix composite. A user material sub-routine model was also written and implemented with the help of FORTRAN subroutines to simulate the macro-mechanical tension test process of Cu + 10 wt% waste steel chips + 5 wt%TiB2 metal matrix composite. The results revealed a good agreement between the micro-mechanical and macro-mechanical finite element analysis models on the one hand and the experimental results on the other. Further, the representative volume element (with matrix and particles) showed about 59% and 66.5% higher tensile strength compared to the matrix–particle interface and the matrix (without particles), respectively. The percentage difference between the micro-mechanical finite element analysis and the experiments as well as the macro-mechanical finite element analysis and the experiments was found to be 5.58% and 9.64%, respectively. The finite element analysis results established that the waste steel chip powder particles exhibited greater stress than the TiB2 powder particles.

“…Wear and specific wear rates are very important parameters in engineering applications. The basic difference between the two parameters is that the wear rate (m 3 /m) is independent of applied load whereas specific wear (m 3 /Nm) is a function of applied load [29]. In this study, the specific wear rate is preferred.…”

This study evaluated the dry sliding wear and friction behaviour of spark plasma sintered Fe-Cr-Ni (a duplex stainless steel known as SAF 2205) matrix with titanium nitride (TiN) nanoparticles as reinforcement. Tests were performed with a tribometer at a relative humidity and temperature of 50 % and 25 °C respectively. Three loads were employed for all 600 cycles tests. Thereafter, the wear mode and mechanism were microscopically examined. Results showed that the coefficient of friction for the nanocomposites were higher than that of the unreinforced SAF 2205 despite showing improved wear performance. Samples with lower TiN compositions exhibited mixed mode of wear mechanism but at higher TiN content, the adhesive mechanism prevails. This study established that increasing the addition of nanosized TiN confers better wear behaviour on spark plasma sintered SAF 2205

In recent years, there has been a significant increase in research studies that include the fabrication and characterization of metal matrix composites (MMCs) with unique features. This comprehensive review delves into the evolution and current status of copper MMCs (Cu‐MMCs) across various industrial sectors. Cu‐MMCs have garnered attention due to their remarkable properties, which include excellent thermal and electrical conductivity, corrosion resistance, and wear resistance. This study explores the fabrication processes, and intricate connections between microstructure and properties of Cu‐MMCs, which encompass ceramic and solid lubricants (SLs) reinforcements. The various types of reinforcement and fabrication methods are examined and highlighted advancements in designing compositions and optimizing microstructures during fabrication. Additionally, this study evaluates the friction and wear characteristics of self‐lubricating hybrid composites, providing insights into effective lubrication ranges and overall tribological behavior patterns. This review highlights that Cu‐MMCs demonstrate superior mechanical strength, wear resistance, and self‐lubricating properties due to ceramics and SLs reinforcements. The mechanisms underlying this behavior involve the formation of a protective transfer layer during sliding and effective lubrication provided by SLs, which reduces direct contact and facilitates smoother interactions between the mating surfaces. The review culminates in an outlook on the prospects of Cu‐MMCs, emphasizing the advantages conferred by their utilization.
