Abstract: Abstract Surface gradient nanostructure of 40Cr steel was prepared by using high frequency impacting and rolling. First, surface nanocrystallization mechanism was investigated through surface morphology, microstructure evolution, work hardening and residual stress. Then friction and… read more here.
