Cryogenic Treatment of Metal – A Review
Materials Today: Proceedings, 2018Abstract Cryogenic Treatment is the subzero process, carried out directly after quenching and proceeded by successive tempering. In cryogenic treatment materials are treated at -196°C for a soaking period of 24 hours. It has shown significant changes in the microstructure and mechanical properties of materials.

Cryogenic neuroablation for the treatment of lower extremity neuromas
The Journal of Foot and Ankle Surgery, 2002A prospective study testing the efficacy of cryosurgery on lower extremity neuromas was performed. Thirty-one neuromas in 20 patients were percutaneously denervated using a Westco Neurostat-III cryoneedle. All patients were surgical candidates who had failed prior conservative treatment.

Classic contributions: cryogenic treatment Deep cryogenic treatment of a D2 cold work tool steel
International Heat Treatment and Surface Engineering, 2008AbstractDeep cryogenic treatment at liquid nitrogen temperatures can enhance the wear resistance of tool steels. This article, first published in 1997, reports experimental investigations that have helped to clarify the underlying mechanisms.

[Cryogenic treatment of rectal tumors].
Minerva medica, 198310 patients with anal or rectal cancers were given liquid nitrogen cryogenic treatment. In 5 cases the treatment was given prior to abdominoperineal amputation of the rectum. The remaining 5 inoperable cases were given the cryogenic treatment alone, followed, in 3 cases by derivative colostomy.

Cold and Cryogenic Treatment of Steel
2013Abstract Cold treating of steel can be used to enhance the transformation of austenite to martensite and improve the stress relief of castings and machined parts. Cryogenic treatment of steel is a distinct process that uses extreme cold to modify the performance of materials.

Deep-cryogenic treatment of ZnO nanowires
Materials Letters, 2013Abstract Deep-cryogenic treatment was performed on vertically aligned ZnO nanowires produced by metal organic chemical vapour deposition. The mechanical response of the nanowires was detected by nanoindentation tests. It was found that Young's modulus, the critical buckling stress and strain of individual nanowires is not significantly influenced by ...

[The treatment of chalazion by cryogenic action].
Oftalmologicheskii zhurnal, 1990The paper describes a proposed and approved method of cryogenic action for treatment of chalazion. Under local anaesthesia by application of 2% or 0.5% instillation of 0.5% dicaine, a two-cycle cryogenic action was conducted for 15-20 seconds through the skin or conjunctiva by means of a cryogenic applicator, cooled by liquid nitrogen, with a removable
