“…Deep cryogenic treatment was shown to improve the wear resistance by 2%-21% in a series of Al-Si alloys [25]. Other research [26][27][28][29] has shown that deep cryogenic treatment causes the grain size to decrease, (e.g., the size of plate martensite [30]), phase transitions (e.g., the transformation of residual austenite into martensite [31]), increased the diffusion of precipitated carbide, and improve the hardness and wear resistance of alloys. The deep cryogenic treatment of magnesium alloys has been shown to refine the microstructures, dissolve the brittle phase, and improve the properties [32][33][34].…”

The influence of deep cryogenic treatment on the microstructure and properties of AlCrFe 2 Ni 2 highentropy alloy were studied by examining its phase composition, microstructure, and properties after cryogenic treatment. The results showed that as the cryogenic treatment increased, the alloy was composed of face-centered cubic (FCC) and body-centered cubic (BCC) phases. As the treatment time increased, the grain orientation of the BCC phase and B2 phase changed and transformed into each other, and the band FCC phase structures became shorter and more disordered. Deep cryogenic treatment effectively improved the hardness, yield strength, and wear resistance of the alloy. The alloy displayed the best performance with a holding time of 4 h, and the Vickers hardness (338 HV) was 11.6% higher than the as-cast alloy, and the yield strength (920 MPa) was 22.7% higher. The friction coefficient was 0.643, and the wear resistance was also significantly improved.

“…It was observed that shallow cryogenic treated and tempered insert performed superbly than other inserts. Hui-Bo He et al [10] studied the performances of various tools while turning AISI 5140 steel under dry cutting condition. Deep cryogenic treated tool delivered an outstanding performance compared to the uncoated and untreated tool.…”

Machinability investigation and cost estimation during finish dry hard turning of AISI 4340 steel with untreated and cryo treated cermet inserts For higher tool life of cutting inserts cryogenic treatment is considered as the most prominent method but no substantial researches have been found concerning the impact of cryogenic treatment on cermet inserts especially in hard turning. Therefore, in the present experimental investigation, the comparative assessment of various responses such as cutting force, flank wear, crater wear, chip morphology and surface roughness were carried out during machining of hardened steel with both untreated and cryo treated cermet ins hard turning erts under dry cutting condition. Lastly, the input variables were optimized using Response surface methodology (RSM) to evaluate the tool life for the economic analysis. The experimental result demonstrated that the uncoated deep cryo treated with tempered cermet insert delivered better results in comparison to other cermet inserts. According to cost analysis, uncoated and deep cryo treated with tempered cermet insert was found to be the most economical among other cermet inserts at the optimum cutting condition.

“…it found that, the best wear resistance was obtained with cutting inserts cryogenically treated for 24 hours. Hui-Bo He et al [15] evaluated performance of uncoated and cryogenic treated tools on the CA6104 lathe. It showed that cryogenic treated inserts have better surface finish and less flank wear than untreated inserts.…”

In the present investigation, an attempt was made to facilitate tool condition monitoring system on cryogenic treated using fuzzy logic and signal processing. Cryogenic treatment is carried out at −196˚C for 48 hours followed on tempering at 200˚C for 2 hours. The AISI4340 steel is machined with cryogenically treated inserts. Speed, feed and depth of cut are selected as input parameters. The results of the proposed method are encouraged in minimizing tool vibration, flank and crater wear. Good correlation is shown between the neural fuzzy and experimental data. As a result, it is found that cryogenically treated inserts have superior tool wear and vibration resistance, and confirmed by conducting further confirmation tests.
