In Situ X?Ray Diffraction Analysis of Microstructure Evolution during Deep Cryogenic Treatment and Tempering of Tool Steels

The Effect of Deep Cryogenic Treatment on Microstructure, Hardness and Wear Behavior of INDRA 5 Cold Work Tool Steel

Investigating the Effect of the Deep Cryogenic Heat Treatment on the Mechanical Properties and Corrosion Behavior of 1.2080 Tool Steel

Deep cryogenic heat treatment is assumed as a supplementary heat treatment performed on steels before the final tempering treatment to enhance the wear resistance and hardness of the steels. In this study, the effects of the deep cryogenic heat treatment on the wear behavior and corrosion resistance of the 1.2080 tool steel were studied using the wear testing machine and polarization and impeda...

The effect of deep cryogenic treatment on mechanical properties of 80CrMo12 5 tool steel

Cryogenic treatment can be used as a supplemental treatment that is performed on some tool steels between quenching and tempering as an effective method for decreasing retained austenite and increasing wear resistance. In this research, the effect of deep cryogenic treatment (DCT) on dimensional stability and mechanical properties of 80CrMo12 5 tool steel was investigated. The martensitic trans...

Deep Cryogenic Treatment of Alloy Steels : A Review

The word, “Cryogenics” is taken from two Greek words – “kryos” which means cold or freezing, and “genes” meaning born or generated. Technologically, it means the study and use of materials (or other requirements) at very low temperatures. In general cryogenic treatment consists of slow cooling already heat treated part to approximately -196C, holding at low temperature up to prescribed period, ...
