On-Site Speaker (Planned) Kaiser Aguirre
Abstract Scope After decades of rigorous development, the high-temperature performance of Ni-based superalloys is beginning to plateau and is ultimately limited by their melting temperature of ~1400C. Multiple material systems that would enable a step-wise change in high-temperature performance with operating temperatures of >1300C are being explored and developed. This research focuses on the characterization of Nb-Si alloys by microindentation and compression testing at room temperature. Test data are correlated to indentation and fracture surface images to elucidate fracture mechanisms of the constituent phases. High temperature microindentation and compression data are also presented.
