Abstract In the current investigation, an exertion is prepared to produce copper-10%tin-nano ZrO2 composites by exploiting melt technique. 4, 8, and 12 wt.% of nano ZrO2 particles are introduced to the copper-tin (Cu-Sn) base network. Microstructural studies are performed by SEM, EDS, and XRD examination. Mechanical portrayal of Cu-10%Sn-4, 8, 12 wt. % of nano ZrO2 composites are measured conferring to ASTM norms. Scanning electron micrographs uncovered the uniform conveyance of nano ZrO2 in the copper-tin amalgam framework. EDX investigation affirmed the presence of Zr and O in nano-ZrO2 built-up composites, and XRD designs uncovered the Cu, Sn, and ZrO2 phases. It is further noticed that hardness, yield strength of Cu-Sn compound increased with the content of 4, 8, and 12 wt.% of nano-ZrO2. Elongation of nano composites diminishes by adding oxide particles. Fractography of tensile examples is completed by utilising SEM micrographs to comprehend the failure of components. Keywords: Cu-Sn alloy, ZrO2 nano particles, stir process, hardness, tensile properties, fractography |
