Abstract

We reported the formation of nanocrystalline structure in the surface layer of a pure tantalum plate under sliding friction treatment. Nanocrystalline grains of 7 nm with amorphous boundaries were formed in the topmost surface layer of Ta plate. Deformation twins were also observed in the nanocrystalline grains with size below 20 nm. Deformation twinning and localized amorphization are the possible deformation mechanisms in the top surface layer of tantalum induced by sliding friction.
