Abstract Scope |
The GRX-810, an oxide-dispersion-strengthened NiCoCr-based alloy, has been recently developed by NASA for aerospace applications. This alloy has been shown to be compatible with additive manufacturing processes. However, before this alloy can be used in load-bearing applications and harsh environments, its mechanical properties; i.e., tensile and fatigue, should be well characterized. This is specifically important since the fatigue behavior of metallic materials have been shown to be very sensitive to manufacturing induced anomalies such as porosity, micro-cracks, lack-of-fusion, surface texture, and inhomogeneous microstructure. Therefore, the focus of this study is to investigate the tensile and fatigue behaviors of additively manufactured GRX-810 across a wide range of temperatures—from cryogenic to elevated. Fractography results will be also presented to reveal the quasi-static and cyclic failure mechanisms of the material at different temperatures. |
