Abstract

Increasing attention is being given to reduce energy consumption and processing time, in conventional melting of metals. The conventional melting of metals has many problems viz. quality of melting, process cost, environmental issues. In the present study an attempt has been made to melt 60Sn40Pb alloyusing microwave hybrid heating technique by exposing the sample to microwave radiations for 5 minutes, carried out in a domestic microwave oven at 2.45 GHz and 900W. The study has been carried out to overcome the drawbacks of conventional melting of metals. The cast metal is investigated under Scanning Electron Microscope (SEM), Elemental Displacement Spectroscope and X-Ray Diffraction (XRD). The microstructure reveals the dispersion of Pb in Sn matrix. XRD graph confirms the presence of various oxides.
