Abstract : This investigation examined the sintering enhancement of refractory metals and attempted to link activator effects to sintering kinetics, microstructure and properties. Work was carried out predominately on the W-Ni-Fe heavy alloy system. In addition, it was recognized that property improvement in heavy alloys could be made possible by understanding impurity-microstructure interactions, fracture behavior, and finally the combined effect of processing conditions and materials characteristics on densification during liquid phase sintering. This report addresses each of the above concerns and presents an overview of the work to date.
