Implication

Randomized trial examines how fatigue frequency and load affect grain growth in nanocrystalline metals, highlighting important factors for material stability.

Key Points

This study investigates how fatigue frequency, load level, and volume confinement affect grain growth kinetics in nanocrystalline nickel.
Examined microstructural evolution under different loading regimes including bulk indentation and micromechanical bending fatigue.
Analyzed the effects of varying fatigue frequencies and load ratios within confined volumes.
Indentation fatigue resulted in grain coarsening primarily within the plastically deformed zone.
Micromechanical bending fatigue led to localized grain growth along cracks, affecting crack propagation.
Higher fatigue frequencies shifted the deformation mode towards material flow and grain alignment.
