“…The performance of M2 high speed steel tools with cryogenic treatment (−196 ∘ C) was assessed using sliding abrasion, hardness tests, and also microstructural analysis. It was found that cryotreatment plays significant role in tool life [1]. A study on M2 tool steel has reported that cryogenic treatment not only facilitates the carbide formation and increases the carbide population and volume fraction in martensite matrix but also can make the carbide distribution more homogeneous.…”

Specimens of M2 were hardened (H) by quenching at 1200∘ C, triple tempered (TTT) at 400 ∘ C, and then cryogenically (C) treated at minus 185 ∘ C for varying lengths of time interval starting from 4 hours to 48 hours of cryosoaking followed by soft tempering at 100 ∘ C to relieve cold stresses (HTC). Underlying wear mechanism, hardness, and impact energy were studied and optimum cryosoaking time was established. It was felt that wear resistance of cryogenically treated material was influenced by the so-called tertiary carbides possibly produced as a result of cryogenic treatment.

“…The research about CT has been validated [1][2][3][4][5][6][7][8][9][10][11][12] by the field tests which have shown enhancement in hardness and durability of tool steels. By the close of the last century, the CT has been tried upon many different varieties of steels, cast iron and nonferrous metals.…”

The effect of dislocation densities and residual stresses is well known in tool steels. Measurement of electrical resistivity in order to monitor dislocation densities or residual stresses has seldom been used in investigating the effect of cryogenic treatment on tool steels.Monitoring residual stresses during cryogenic treatment becomes important as it is directly related to changes due to cryogenic treatment of tool steels. For high carbon high chromium (HCHC-AISI D2) steels, not only wear resistance but dimensional stability is an important issue as the steels are extensively used in dies, precision measuring instruments.This work comprises of study of measurement of electrical resistivity of AISI D2 steel at various stages of cryogenic treatment. Use of these measurements in order to assess the dimensional stability of these steels is discussed in this paper.

“…We do not know of a research in the literature that would resolve the influence of heat-treatment conditions on the properties of this steel. However, C/M high-speed steel 1.3343 (AISI M2) is often used for cryogenic treatment according to references, 6,[11][12] as it has low carbon and vanadium contents in comparison with the other type of steel. Reference 12 notes that no significant impact of DCT on the final hardness of steel 1.3343 was not proven, while its positive effect on the wear resistance was demonstrated.…”

Tool steels produced with powder metallurgy (P/M) are perspective materials, although they are more expensive in comparison with tool steels produced with the conventional method. The work focuses on the study of mechanical properties and structure depending on the heat-treatment conditions for the two tool steels. These are the 1.2379 steel for cold work produced with classical metallurgy and high-speed P/M steel Vanadis 23. Both materials were heat treated in the conventional manner to achieve a hardness of 61 HRC. They were also exposed to a cryogenic treatment at temperatures of -90°C and -196°C for 4 h between the hardening and the tempering. We evaluated the hardness and strength using the three-point-bending test and the wear resistance using the pin-on-disk method. Keywords: powder metallurgy, high-speed steels, heat treatment, cryogenic treatment, wear rate Orodna jekla, proizvedena s postopki metalurgije v prahu (angl. P/M) so perspektivni materiali, kljub temu da so dra`ji od tistih izdelanih s konvencionalno metodo. Delo je osredoto~eno na {tudijo mehanskih lastnosti in strukturo, v odvisnosti od pogojev toplotne obdelave za ti dve vrsti orodnih jekel. To so jekla 1.2379 za delo v hladnem, proizvedena s klasi~nimi metalur{kimi postopki in hitrorezno P/M jeklo Vanadis 23. Oba materiala sta bila toplotno obdelana s konvencionalnimi postopki, glede na njuno sestavo, tako, da sta dosegli trdnost 61 HRC. Bili sta tudi izpostavljeni obdelavi s podhlajevanjem pri temperaturah od -90°C in -196°C za 4 h med strjevanjem in temperiranjem. Trdnost je bila ocenjena pri trito~kovnem mehanskem testu (zvijanje) in s testom obrabe po metodi pin-on-disk. Klju~ne besede: metalurgija prahov, visokorezna jekla, toplotna obdelava, obdelava s podhlajevanjem, stopnja obrabe
