| Abstract Scope |
The success of friction stir welding (FSW) and related technologies on materials such as aluminum and magnesium alloys is owed to the superior properties of the processed material that are associated with the absence of melting and solidification during the solid-state processes. However, the commercial application of these technologies on steels and other non-ferrous high-strength, high-temperature materials is limited due to the high cost and short lifetimes of the available tool materials. To overcome this, Integrated Computational Materials Engineering (ICME) combined with experimental prototyping validation has been adopted to design next-generation tools specific to workpiece materials. Cermet tools with tungsten carbide or niobium carbide as the hard phase with a high entropy alloy binder are processed via mechanical alloying and spark plasma sintering and their feasibility and effectiveness are evaluated for FSW and related technologies. Results from the experimental prototyping and testing effort will be presented and discussed in-depth. |
