1. Introduction

The purpose of applying cryogenic treatment is to improve some mechanical properties of materials by changing microstructure so as to enhance service performance or extend the service life of tools or parts [5 10.1016/S0266-3538(96)00153-4 DeepDyveJun 11, 2020 · 10.1016/S0266-3538(96)00153-4 10.1016/S0266-3538(96)00153-4 2020-06-11 00:00:00 A procedure is suggested of evaluating the efjiciency of fiber treatments by the extent to which the fiber reinforcement strength is realized in the composite. For this purpose, the effects of surface treatments on the scale effect of carbon-fiber strength and adhesion to epoxy resin and polyamide matrices was

Tribol (April,2019) Advanced Braze Alloys for Fast Epitaxial High-Temperature Brazing of Single-Crystalline Nickel-Base Superalloys Advanced Engineering Materials:Vol 21, No 7Jul 17, 2019 · A new process combing equal channel angular pressing (ECAP) and deep cryogenic treatment (DCT) is proposed to balance the tensile strength and electrical conductivity of pure copper. The combination of tensile strength 423 MPa and electrical conductivity 97.9% IACS is simultaneously achieved after ECAP and DCT due to the increase of CRYOGENIC TREATMENT AND ITS EFFECT ON TOOL STEELfollows deep cryogenic treatment, and lengthens the tool life as the amount of -carbides increases. The amount of-carbides that forms is directly proportional to the tempering time and temperature. Typical heat treatment cycle using cryogenic treatment can be seen in Fig. 4 CRYOGENIC TREATMENT AND ITS EFFECT ON MECHANICAL PROPERTIES

Nov 20, 2019 · Bensely et al have experimented case carburized steel (En 353) under deep cryogenic treatment performed at 423 K for soaking periods of 1.5 h. It was inferred from the studies that the wear resistance has been considerably increased due to cryogenic treatment and deep cryogenic treatment includes much more improvement than shallow cryogenic Design of Metal Matrix Composite with Particle ReinforcementJan 16, 2015 · Similar to behavior of composites, scanning electron microscopy (SEM) image of debonding M23C6 particles from matrix of deep cryogenic treated 45WCrV7 [2] and AISI D2 [3] steels, and that of breaking down M7C3 particles have been observed [3].

IOSR JournalDeep cryogenic treatment (DCT) was carried out on Cryocan at 77K. Various combinations of heat treatment cycles were performed to improve the mechanical properties of EN31 steel. This experimental also investigated the role of multiple cryogenic treatments before and after tempering.
