Abstract
In this article we present the results of the simulation of a hybrid heat treatment methodology for materials, by using electromagnetic waves in the microwave range and the thermal power radiation of an electrical resistance. This resistance was placed in such a way that only half of the solid (a two-layers sphere) receives its energy. Then, it was controlled to produce a constant and uniform heat flow. In addition, for the present case, materials with different thermophysical properties were defined in each layer, which were considered to be invariant both with position and with temperature. The heat flow was considered constant over time. The temperature profiles for each layer showed variations in time and position, so it was observed that this simultaneous heating eases the adjustment of these profiles, according to the needs of thermal treatment. Thus, the advantage of hybrid heating was evidenced.
