“…It was determined that the cryogenic process and the tempering process applied afterward achieved a 77 and 126 % improvement in drill lives, respectively. Amini et al [29] investigated the effect of holding time (24-120 h) at a liquid nitrogen temperature during the DCT on the microstructural changes of AISI D3 tool steel. They showed that the hardness, microhardness, microstructure uniformity and carbide percentage reached their optimum values with a 36 h holding duration.…”

“…Several researchers Average coefficient of friction have cited the worthiness of CT and its influence on the modification of the morphology of microstructures and enhancement in hardness of the CWS and HDS [4−7]. Tribological behavior of CWS 80CrMo12 5 was examined by Amini et al [8] at different cryo-treatment holding times (i.e., 0, 6, 24, 48, 72, and 168 h); sliding velocity: 0.1, 0.15, and 0.2 m/s; load: 120 N and 160 N; up to 1,000 m. They concluded that 48 h soaking time at deep cryogenic temperature is optimum to achieve maximum wear resistance. Das et al [9] demonstrated the influence of varied cryo-treatment on dry sliding wear behavior of AISI D2 CWS at different holding times (i.e., 0, 12, 36, 60, and 84 h) at different operating parameters of load and sliding velocity in a pinon-disk wear test.…”

Abstract:Cryogenic treatment (CT) is a relatively new field, which has emerged during the last three decades of the twentieth century. However, its impact on material shaping and making tool life, and enhancement of their mechanical properties are quite remarkable. The selection of appropriate process parameters for CT is essential for cost reduction and optimum productivity. This study focuses on the influence of key parameters of CT cycles (i.e., soaking temperature and duration) on the friction and wear behavior of AISI H13 hot die steel under dry sliding conditions against hardened and tempered AISI D3 cold work tool steel (counter face) at varying sliding speeds and loads. Mathematical models have been developed for wear rate, the average coefficient of friction, and maximum contact temperature using the Box-Cox methodology. The developed mathematical models have been validated by comparing with the experimental results. Moreover, the optimum values of the process parameter have been employed to maximize the output and validate the same by confirmation of the experiments. To the best of our knowledge, this is the first study that demonstrates the modeling and optimization of sliding friction and wear characteristics of AISI H13 under varied CT cycles.

“…Optimum temperatures were determined at which significant relaxation occurred without adversely affecting the microstructure and mechanical behavior of the material. And, cryogenic treatment of die steel for achieving improvement in abrasion resistance and dimensional stability has become the topic of current research interest [7][8][9][10][11]. The above review indicates that most of studies were focused on the effect of processing mode and temperatures in heat treatment on grinding machinability and surface integrity.…”

This paper investigated the grinding machinability and surface integrity of premium thread gauge material 9Mn2V in conventional surface grinding by using seeded gel (SG) abrasive (3SG80KV) under different heat treatment processes. Serious meshy segregation of carbide, excessive amounts of retained austenite, coarse and inhomogeneous distribution of material structure were significant causes of grinding burn and grinding crack. In order to improve the abrasion resistance and mechanical properties of workpiece material, cryogenic and tempering treatment was added. After adopting cryogenic and tempering treatment for two times, the disappearance of the meshy segregated carbide and network carbide was eliminated, the amount of the retained austenite content was within 4 %, and martensite became much more fine and homogeneous. The grinding experiment results indicated that workpiece material 9Mn2V could provide superior grinding integrity with the occurrence of grinding burn and grinding cracks reduced by using this process.
