MICROWAVE SINTERING OF METALLIC POWDER COMBINED WITH UNIAXIAL PRESSURE

摘要

The first reporting of microwave sintering of ceramics appeared during the 1970's. Microwave sintering of materials is completely different from conventional sintering. Indeed, conventional sintering involves a mechanism of heat transfer by radiation, conduction and convection, so the material is heated from the surface to the inside by thermal conduction In opposite, it is very well know that in microwave sintering, heating is due to the conversion of electromagnetic energy into thermal energy [1] [2] [3]. In this process, the heat is generated within the material first and then heat the entire volume, which is frequently named as volumetric heating.
