Two-Phase Functionally Graded Tantalum Carbide

Invention SummaryHard materials resist wear, but are more prone to fracture. Tough materials resist fracture, but are more susceptible to wear. Generally, it is difficult to design a material that is both hard and tough. This invention seeks to balance these considerations by providing a two-phase material that exhibits both high hardness and high fracture...

Pressure-less Method for Binding Tantalum Carbides

Invention SummaryThis technology is a novel and low-cost method for binding tantalum carbides. This method is known as pressure-less sintering and only requires certain levels of heat to bond tantalum carbides. Most existing methods require both heat and pressure, necessitating more elaborate manufacturing processes. Currently, this method is used...

High-Toughness Tantalum Carbide for High-Temperature Applications

Invention SummaryTantalum Carbide (TaC) is an extremely hard refractory ceramic material with high temperature resistance. Researchers at the University of Utah have discovered a form of tantalum carbide called zeta phase with three times more fracture toughness than the more common TaC form. The TaC zeta form offers high strength, high fracture toughness...
