| Abstract Scope |
Flash sintering (FS) and ultrafast high-temperature sintering (UHS) have beed proposed in the last years as techniques that allow the densification of ceramics in short time and using limited amount of energy. The approaches are extremely promising although their application at the industrial level still requires numerous investigative and validation actions. An area where FS and UHS can make a difference is that of the refractory ceramics like carbides and borides which usually require very high temperature under the action of significant pressures or the addition of sintering aids.
In the present work, the application of FS and UHS on tungsten carbide, titanium carbide, zirconium diboride and their composites is presented. The conditions for inducing the thermal runaway phenomenon upon FS in the considered metal-like compounds are studied. The processing condition necessary for achieving high density are analysed also in terms of the final microstructure of the materials. |
