Abstract Scope |
Obtaining bulk materials properties like strength, tensile ductility, and fracture toughness of expensive and difficult-to-process metals like refractory alloys using traditional methods is challenging and time-consuming. Surface-based (scratch) methods offer a significantly faster alternative approach, enabling bulk mechanical properties to be determined without the need for the extensive preparation of numerous and large test specimens. Scratch-based methods offer opportunities that complement multiscale indentation, further facilitating rapid alloy development by overcoming traditional limitations and accelerating materials discovery. Examples of how these methods are being used to support alloy development for extreme environment applications will be discussed, e.g., new W-based alloys for fusion plasma containment and refractory multi-principal-element alloys for gas turbine engines. |
