“…Similar to behavior of composites, scanning electron microscopy (SEM) image of debonding M 23 C 6 particles from matrix of deep cryogenic treated 45WCrV7 [2] and AISI D2 [3] steels, and that of breaking down M 7 C 3 particles have been observed [3]. Also, in force-displacement (F-∆L) curve of deep cryogenic treated 1.2542 steel, the elastic part contains several slopes [4].…”

Abstract:Using the methods which are applied for estimating strength and toughness of composites reduces trial-and-error rate in their design. One of the mechanisms for strengthening and increasing toughness of composites is through debonding mechanism. Interface strength of reinforcement with matrix and effective surface of debonding greatly affect toughness and strength of these types of materials. In this study, a model was proposed to estimate the effect of interface and matrix strength of composites in increasing tensile toughness and strength. Then, interface strength and its effect in increasing tensile toughness and strength were calculated in a case study of composites containing particle reinforcement in matrix of steel.

“…The cryosoaking duration was optimised at 16 h and at optimum cryosoaking duration highest carbide density, highest hardness, and lowest wear rate was reported. In the study of the effect of cryotreatment on mechanical properties of 1.2542 tool steel (Fe-0.48C-0.33Mn-0.99Si-1.12Cr-1.57W), Farhani et al 3 carried out hardening, oil or air quenching, single tempering and cryotreatment. It was reported that the 48 h cryosoaking duration improves the tensile strength, hardness, and ductility.…”

“…It has been reported that the wear resistance by deep cryogenic treatment is very high compared to the shallow cryogenic treatment 1 . DCT improves not only the surface but also an entire cross-section of material or specimen or component 2 , with the objective of improving the carbide distribution pattern, as this modification has a positive effect on hardness, wear resistance, fracture toughness by causing structural homogeneity 3 . Also, DCT could improve the service life by improving the wear resistance of the tool steels 1,4 .…”

The aim of the present work was to find out the optimum cryosoaking duration of deep cryogenic treatment to reduce the wear rate. The AISI H21 hot work tool steel specimens were hardened at 1195 ºC, cryotreated at-185 ºC for 6 to 30 h, double tempered at 540 ºC and soft tempered at 100 ºC. The hardness, impact toughness, wear rate and microstructural characteristics of the cryotreated specimens were studied. Wear test parameters were optimized by using Taguchi technique. Analysis of variance and signal to noise ratio were carried out in order to find significant parameters affecting the dependent parameter. The results show that load is the most influencing parameter followed by sliding velocity and cryosoaking duration. The linear mathematical model has been developed for wear rate using a regression analysis technique which will be useful for predicting results for new experiments.

“…Indeed the mechanical properties of 1.2542 [10] can also be improved through deep cryogenic treatment. In reality, the most exciting point is that the elongation also is raised by 12% -35% while the tensile strength and hardness are improved by 32% -36% and 12% respectively when a cryogenic treatment at −196˚C with maintaining periods of 24 -48 hours after quenching, and tempering at 200˚C is implemented.…”

Cryogenic treatment has been increasingly applied to enhance the hardness, antiwear ability and fatigue performance of die steel. On the basis of reading a large number of research papers and references across the world, the author makes a detailed analysis and brief summary of the influence of cryogenic treatment on microstructure after quenching process or quenching plus tempering process, on first and second carbides, on content of retained austenite, on surface hardness, on mechanical properties and antiwear ability of die steels. It's proved that cryogenic treatment on die steel significantly improves its hardness, antiwear capacity and service life. It's the cryogenic process to make die steel have higher hardness, better antiwear ability, better ductility and longer service life because cryogenic process actually has a good influence on die steel of its microstructure, retained austenite volume and amount and size of the second carbide.
