Abstract Scope |
This work investigates the nano-scratch behavior of a laser powder-bed fusion (L-PBF) 3D-printed multiphase high-entropy alloy (HEA). Multiphase HEAs have garnered considerable attention in recent years due to their exceptional mechanical and functional properties. However, understanding their response to scratching and abrasion forces at the nanoscale is crucial for their potential applications in various industries. The nano-scratch tests are performed under controlled loads and displacement rates to systematically study the material's behavior during scratching. The resulting load-depth curves are analyzed to determine the hardness, elastic modulus, and plastic deformation mechanisms of the 3D-printed HEAs. Preliminary findings indicate that 3D-printed HEAs exhibit interesting nano-scratch behavior compared to conventional alloys. This research contributes to the understanding of the scratch and abrasion resistance of 3D-printed HEAs, facilitating the optimization of their mechanical performance and guiding their application in industries requiring durable and functional materials. |
