A hollow circular cylinder specimen with an annular U-notch of chrome molybdenum steel with 0.20 mass% C (SCM420) was carburized in carrier gas and quenched in oil bath.
In order to determine the case depth, the specimen was cut off and carbon content and Vickers hardness gradients were measured experimentally near the carburized surface.
The residual strain mapping in the interior of carburized cylinder was conducted nondestructively by neutron strain scanning. The neutron diffraction from Fe-211 plane was used for strain scanning.
