Abstract

In order to properly understand the behavior of metal powders during microwave sintering, it is important to be able to observe material property changes in situ. One of the best ways to do this is by performing the sintering inside a microwave cavity resonator (MCR). MCRs spatially separate the magnetic and electric fields allowing the interaction with each to be studied in isolation. They also allow the determination of material properties by evaluating the unloaded Q. In this paper initial results are presented showing the changes in unloaded Q of a quasi-spherical cavity being used to heat samples of titanium (Ti64) powder. Partial sintering was confirmed in the sample by a significant and permanent reduction in absorption indicated by a sharp rise in the Q.
