Abstract

Microwave material processing is a rapid and cost-effective method with significant advantages over conventional methods of material processing. The present study focuses on the finite element analysis of melting of bulk metals such as aluminum alloy (Al-7039), magnesium alloy (Mg-AZ31B), and lead using microwave energy at a maximum input power of 1400 W. The simulation study was carried out using COMSOL Multiphysics. A silicon carbide susceptor was used for initial microwave coupling and heating the bulk metal via the conventional mode of heat transfer. Once the bulk metal reaches a critical temperature, the bulk metal gets heated using both conventional and microwave modes of heating. The finite element analysis has been used to describe the time at which these bulk metals start melting. The effect of different input power and casting volume on electric field distribution and time–temperature profile of metals has also been discussed.
