Common cryogenic treatment temperature profile was shown in Fig. 2. The different categories of cryogenic treatment are (a) Shallow cryogenic treatment (SCT) will have specimen temperature of -80 °C, (b) Deep cryogenic treatment (DCT) having the cooling temperature of 196 °C, followed by slowly warming to room. Material and …

Effect of deep cryogenic treatment and hardness vs. fracture toughness ratio on tool steel wear resistance was determined under reciprocating sliding conditions using ball-on-flat configuration, stroke length of 4 mm and frequency of 15 Hz (Fig. 1 a). With the aim to concentrate all the wear on the tool steel disc (Φ 20 × 8 mm) WC ball (Φ 32 mm) …

After deep cryogenic treatment, the percentage of carbides increases significantly and also shows a more uniform distribution, which is not observed in the shallow cryogenic treatment. Compared with shallow cryogenic treatment, deep cryogenic treatment can reduce the content of residual austenite to a greater extent, which also …

Deep cryogenic treatment (DCT) of steels and other materials is a distinct process that uses the application of extreme cold applied with distinct time/temperature profiles to modify the performance of materials. This process is also referred to as cryogenic processing, cryogenic tempering, deep cryogenic …

Deep cryogenic treatment proves to be a solution for this problem. In deep cryogenic processing parts are cooled to more than 300°C below zero compared to about -120°C used in conventional cryogenic processing. Deep cryogenic processing involves cooling parts at a controlled rate which is governed by a microprocessor [4].
