Surface Hardening: Hard Turning or Grinding?

The measured low microhardness value in subsurface may easily lead to a misunderstanding of surface material properties. This study shows that the apparent softening is not due to thermal effects, but rather is caused by the lack of material between the indented area and top surface, which results in less resistance to deformation by a microindenter.Get price
