The Effect of Cryogenic Treatment on Distribution of Residual Stress in Case Carburized En 353 Steel

The effect of cryogenic treatment on the distribution of the residual stress in case carburized steel (En 353) was studied using X-Ray diffraction techniques.  X-Ray diffraction consistently shows a significant reduction in hoop tensile and compressive stresses as a result of deep cryogenic processing.  Two types of cryogenic treatment: shallow cryogenic treatment (193 K) and deep cryogenic treatment (77 K) were adopted as a supplement to conventional heat treatment in these studies.
