Significant Improvement in Wear Resistance of CoCrFeNi High-Entropy Alloy via Boron Doping

open access: yesLubricants, 2023
CoCrFeNi high-entropy alloy (HEA) exhibits excellent mechanical properties but relatively poor wear resistance. In particular, when the load reaches a certain level and the deformation mechanism of the CoCrFeNi HEA changes, the formation of shear bands ...

Stress-dependent subsurface structural transformations of gradient nanograin Ti–6Al–4V alloy and its impact on wear behavior

open access: yesJournal of Materials Research and Technology, 2023
Gradient nanograin (GNG) metals possess outstanding resistance to sliding friction and wear. The tribolayer plays a major role in the wear performance of metals. However, the current understanding of the tribolayer in GNG metals is still limited.
