Molecular dynamics study of the friction deformation mechanism and inverse Hall–Petch effect in Ni–Cr–Fe polycrystalline alloys with different grain sizes under tensile-vibrational friction coupling
During service in critical components such as aircraft engine blades, nickel-based high-temperature alloys are subjected to the coupled effects of tensile stress and vibration friction. However, the failure mechanisms involved remain unclear. Grain refinement is a key method for improving the comprehensive mechanical p...
