Due to the sensibility of micro hardness values on dislocation density (normally increases after after plastic deformation),the surface hardened layer can be indirectly evaluated by micro hardness measurement.
Since the micro hardness values are very sensitive to dislocation density which increases after plastic deformation, the surface hardened layer can be indirectly evaluated by micro hardness measurement, |
