| Abstract Scope |
Obtaining the tensile strength, hardness, and fracture toughness of certain refractory alloys and polycrystalline materials using traditional methods can be expensive and challenging. Using a multifunctional mechanical testing platform, we can use surface-based scratch methods to get tensile equivalent and scalable data without the materials synthesis requirements of traditional tensile testing.
Previous work has demonstrated that fracture toughness can be determined from crack spacing and size resulting from a scratch. Mechanical testing through this method can enable rapid alloy development and optimization for theory-guided alloy design. It can also be used to determine tensile ductility for refractory alloys, investigate temperature dependencies in strength and ductility, and gain insights into complex phenomena such as hydrogen embrittlement.
Utilization of this method will enable materials design for HEAs and refractory MEPAs not possible with traditional methods due to synthesizing requirements. This method could accelerate the development of advanced materials. |
