Paper Title:
Enhanced Saturation Magnetization of Nanocrystalline Cobalt Produced by Surface Mechanical Attrition Treatment
  Abstract

A nanocrystalline surface layer is produced in Co plate by surface mechanical attrition treatment (SMAT). The characterization of microstructure and composition indicates that elements of Fe, Cr diffuse from hardened steel balls into the surface layer during SMAT. The diffusion phenomenon results in the composition deviation in the surface layer, leading to higher value of saturation magnetization (Ms) for nanocrystalline Co surface layer in comparison with its coarse-grained counterpart.
