Freeze cycle processing

Freeze Cycle Processing is the name of a process from the group of cryogenic treatments in which materials are to undergo a structural change through cooling with liquid nitrogen at a temperature of approx. −183  ° C. Tensions are reduced by diffusive processes during the holding time in the cryogenic state .

Structural defects are partially healed, and materials that contain retained austenite are converted into martensite .

Blades and production tools treated in this way are intended to have an improved service life.
