“…Recently, Govind et al investigated the impact of varying wt% of Si 3 N 4 (5,10,15) on the mechanical and physical properties of Cu-10Sn alloys. The study revealed that the composite with 5 wt% of Si 3 N 4 shows optimal properties [30]. This divulges the incredible resistance of Si 3 N 4 towards thermal shocks and its wear resistance, making it very suitable for tribological applications.…”

“…The final melt obtained was fed into a permanent diecast mould coated with LUBRIKOTE die coat material at a temperature of 1150 °C to produce rods with a radius of 16 mm and a length of 140 mm, as shown in Figure 4. Advanced characterization techniques (FESEM, TEM, and XRD) were used to characterize the fabricated baseline alloy and MMCs, which have already been reported in our previous publication [30]. Table 1 depicts the wt% of Si3N4 samples used in the current investigation.…”

“…The investigation of uniform distribution and the inclusion of Si 3 N 4 particles within the matrix was carried out through FESEM analysis of all the manufactured specimens. The FESEM analysis and elemental mapping, and EDS study on each piece were investigated in detail in our previous investigation of Govind et al [30]. Almost five samples were subjected to optical arc spectroscopy (FoundryMaster expert, Germany) to obtain the elemental composition of the regular bronze Cu-10Sn alloy.…”

“…An in-depth TEM analysis was conducted on Sample B (Si 3 N 4 embedded α-Cu matrix) of the fabricated composites to analyze the ceramic particle distribution, bonding, and dislocation with the matrix in the first part of this investigation by Govind et al [30]. The TEM study was a combination of analyzing dark-field, bright-field images, and SAED (Selected Area Electron Diffraction) patterns on the mentioned sample.…”

Bronze metal matrix composites (MMCs) are futuristic materials that may find applications in automobile, aviation, and marine industries, specifically for propellers in submarines, bearings, and bushings for defence purposes. The present investigation studied the effect of Si3N4 (5, 10, 15 wt%) ceramic particles on the physical, metallurgical, and tribological behaviour of Cu-10Sn/Si3N4 MMCs. Cast rods of three composites and a base alloy were fabricated using the liquid metallurgy route. The microstructural characterisation for the cast samples was conducted using FESEM (Field Emission Scanning Electron Microscope), EDS (Energy Dispersive Spectroscopy), XRD (X-ray diffraction), and TEM (Transmission Electron Microscope), which revealed that the Cu-10Sn alloy reinforced with 5 wt% of Si3N4 had homogeneous distribution and perfect bonding of the Si3N4 with the bronze MMC. The dry sliding wear test was performed by varying parameters such as the applied load (10, 20, 30 N) and sliding velocity (1, 2, 3 m/s). The specific wear rate (SWR) increased against an increased load. However, the SWR and coefficient of friction decreased and then increased against an increasing sliding velocity due to tribolayer formation. The primary wear mechanism observed at low and high loads was severe delamination. In contrast, the wear mechanism was adhesion wear at high and low velocities. Amongst the researched samples, Cu-10Sn/5 wt% Si3N4 composites revealed the least SWR at a load of 10 N and sliding velocity of 2 m/s and hence can be recommended for manufacturing bearings and bushings in the automobile and defence industry.

“…Metal matrix composites have drawn significant attention from various industries, particularly heavy industries, and are increasingly used in many fields such as aerospace, the automobile industry, biomedicine, and electronic packaging. This is due to their high specific strength and stiffness [4][5][6][7]. SMA is a brand-new class of smart material that possesses special qualities like superelasticity, temperature phase transition, and pre-strain.…”

The constitutive model and modulus parameter equivalence of shape memory alloy composites (SMAC) serve as the foundation for the structural dynamic modeling of composite materials, which has a direct impact on the dynamic characteristics and modeling accuracy of SMAC. This article proposes a homogenization method for SMA composites considering interfacial phases, models the interface stress transfer of three-phase cylinders physically, and derives the axial and shear stresses of SMA fiber phase, interfacial phase, and matrix phase mathematically. The homogenization method and stress expression were then used to determine the macroscopic effective modulus of SMAC as well as the stress characteristics of the fiber phase and interface phase of SMA. The findings demonstrate the significance of volume fraction and tensile pre-strain in stress transfer between the fiber phase and interface phase at high temperatures. The maximum axial stress in the fiber phase is 705.05 MPa when the SMA is fully austenitic and the pre-strain increases to 5%. At 10% volume fraction of SMA, the fiber phase’s maximum axial stress can reach 1000 MPa. Ultimately, an experimental verification of the theoretical calculation method’s accuracy for the effective modulus of SMAC lays the groundwork for the dynamic modeling of SMAC structures.
