Abstract

Field activated sintering is receiving a growing attention as an alternative to classical sintering for its unique ability to realize high level of densification at low temperatures and using short processing times. This technique, however, is characterized by the presence of complex temperature and stress distributions and, as a result, microstructural non-uniformities may be produced in the samples. These temperature non-homogeneities depend on a large number of experimental parameters, such as die geometry, heating rate, material properties, sintering temperature, etc. In this paper, the various experimental parameters are systematically analyzed in order to evidence their role in determining the temperature distribution. Methods to control or remove temperature inhomogeneities will be discussed, particularly in the case of large samples.
