Summary:Microwave sintering of metal powder compacts is simulated within a simple semi-analytical multiphysics model taking into account the effective dielectric and magnetic properties. It is demonstrated that microwave heating exhibits resonant behavior which facilitates rapid densification of powder metals in a way similar to flash sintering. Rapid, stable and efficient microwave sintering regimes can be implemented by using adaptive control over the intensity and/or frequency of the microwave radiation. [Display omitted]
