Abstract Scope |
Mechanical alloying followed by spark plasma sintering (SPS) or pressure less sintering were used to prototype various NbC-Ni cermet compositions. The effect of various process parameters related to the ball milling and sintering processes on the final microstructure and mechanical properties of these NbC-Ni cermet compositions were evaluated. Further, based on the experimental observations, computational modeling tools were used to predict changes in the microstructure and properties for the NbC-Ni system in general. The goal of this effort was to narrow down on the right composition and process parameters that would work for prototyping a suitable cermet to be used to make friction stir welding (FSW) tools to process high-temperature materials. A systematic investigation has been carried out on the NbC-Ni system to gain a better understanding of the processing-structure-property relationship and lay a foundation for developing novel cermet-based tools for FSW. |
