“…Das et al 6 established that the 36 h cryosoaking time provides the highest hardness of AISI D2 tool steel. Das et al 32 and Korade et al 33 reported near about 5 % improvement in the hardness of cryotreated AISI D2 tool steel. In the study of the influence of cryotreatment on H13 die steel, Shinde and Dhokey 34 observed that approximately 10 % improvement in hardness.…”

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.

“…AISI D2 tool steel has high wear and abrasion resistance. High alloying content may provide excellent hardenability and good dimensional stability [6] since the parts are suitable to air quenching. This grade of steel is widely used for cold working, especially for cutting tools and dies production [7,8].…”

New materials and heat treatment are being developed worldwide to improve tool life. Tool steels are expensive due to the alloying elements and fabrication costs. Therefore, the maximization of tool life keeping good surface finishing is especially important to keep the processes attractiveness. The application of cryogenic treatment is promising to enhance mechanical and metallurgical properties of cold work tool steel parts. The possibility of increasing the finer secondary carbides content and decreasing amount of retained austenite during deep cryogenic treatment (DCT) is also an important matter for industry. The aim of this work is to improve tool life by applying DCT in AISI D2 cutting punches and compare these results with punches treated by conventional heat treatment (CHT), vacuum furnace quenching plus triple tempering.The tests used for analyses were: metallography, X-ray diffraction, carbides fraction, hardness and number of parts produced by each punch (practical test). The results indicate that the DCT punches have an enhancement of approximately 50% in its useful life.

“…DCT usually involves cooling the steel by immersing it in liquid nitrogen. The resulting changes in the substructure of the martensite that forms at cryogenic temperatures may produce improvement in wear behavior [6][7][8]. Compared to conventional treatment, DCT increases the number of carbide precipitates and the homogeneity of their distribution [9,10].…”

The influence of deep cryogenic treatment (DCT) on microstructure and tribological property of M2 high speed steel by means of nanoscratch and internal friction were discussed. The results obtained have shown that the wear resistance of M2 high speed steel after DCT treatment was superior to that of quenched samples. The formation of alloy carbides affected the height of the Snoek-Köster-Kê (SKK) peak during cryogenic treatment, making the decrease of the SKK peak. Long-time isothermal cryogenic treatment is not benefit for frictional properties of M2 high speed steel.
