| Abstract Scope |
Nickel-based superalloys are vital in numerous roles in industry. Their unique combinations of properties allow them to excel in highly demanding environments where other materials would fail. It is not one exceptional property, but a combination of high-temperature strength, toughness, and oxidation and corrosion resistance that makes this class of alloys unique. Recent alloy development has focused on tailoring specific properties for certain applications. An example of an emerging alloy is Haynes® 244®, a high strength, high temperature alloy with a very low coefficient of thermal expansion for use in applications with very specific dimensional tolerances such as gas turbine rings and seals. This alloy is strengthened through a novel intermetallic phase not found in other superalloys. However, the deformation mechanisms of this alloy are not well understood, and the presented research aims to elucidate the nature of dislocation motion in this alloy. |
