| Outline of Final Research Achievements |
The effect of lattice defects on the tribological behavior for low / high friction coefficient under lubricant was investigated in the nanostructured pure Fe produced by heavy plastic deformation or physical vapor deposition methods. In the nanostructured pure Fe with high-density of lattice defects (grain boundary, dislocation and so on), the tribological behavior was improved in comparison with the conventional pure Fe. This phenomenon occurs by controlling microstructure in materials irrespective of production methods.
