Effect of nano size copper addition on the tensile properties of tin

Abstract

In the present study, varying volume fraction of nano-size copper (0 vol. %, 0.2 vol. % and 0.35 vol. %) particulates were incorporated into tin using powder metallurgy method with microwave assisted sintering. Microstructural characterization studies conducted on the extruded samples showed reasonably uniform distribution of secondary phase, near equiaxed grain morphology and the presence of minimal porosity in all cases. Room temperature tensile test results revealed that strength level increases with the addition of nano copper while ductility decreases. An attempt has been made to correlate the effect of copper addition on the tensile properties of tin.
