| Abstract Scope |
Single-crystal superalloys are highly valuable in the aerospace industry due to their exceptional properties in extreme environments such as jet engines and other turbomachinery. Among these superalloys, Nickel-based alloys have exceptional strength and creep resistance at high temperatures, and Titanium-based alloys possess highly tunable properties. However, single-crystal alloys exhibit mechanical properties that are strongly coupled to the crystallographic orientation, and understanding this structure-property dependence is critical to the design and implementation of these alloys. In this study, we investigate the elastic and plastic anisotropy of three superalloys: CMSX-4, PWA 1480, and Ti-15Mo. We will employ orientation-dependent nanomechanical testing and analyze the mechanical properties, namely, hardness, elastic modulus, and creep resistance of the materials in different orientations from load-displacement curves. |
