چکیده
In this paper effect of cryogenic treatment on mechanical properties of cold work tool steels at various combination of heat treatment cycle (process sequence) are studied. The material selected for these processes are AISI D2 and D3.Cryogenic treatment is commonly referred as cryotreatment, is an add-on process to the conventional heat treatment of tool steel. Cryogenic treatment improves hardness, microstructure of metal (retained austenite to marten site), dimensional stability and decreases residual stresses. The effects of these process sequences of cryotreatment on properties of tool steel were studied by conducting some laboratory tests. Study of microstructure characterization of different specimens is carried out using optical microscope. Also hardness measurement was done by using Vickers indentation method.

The effect of deep cryogenic treatment on mechanical properties of 80CrMo12 5 tool steel
Cryogenic treatment can be used as a supplemental treatment that is performed on some tool steels between quenching and tempering as an effective method for decreasing retained austenite and increasing wear resistance. In this research, the effect of deep cryogenic treatment (DCT) on dimensional stability and mechanical properties of 80CrMo12 5 tool steel was investigated. The martensitic trans...

The deep cryogenic treatment is a complementary operation that is done on a variety of tool steels aimed at improving their abrasion resistance and hardness. In the case of the H13 hot-work steel, which is widely used at high temperatures as a hot-deformation tool, we need to determine the efficiency of subzero treatment on it at the working temperature. In this regard, this paper is focu...

The effect of microstructural refinement and intercritical annealing on the mechanical properties and work-hardening response of a low carbon St12 steel was studied. It was revealed that intercritical annealing of the ferritic-pearlitic sheet results in the formation of a coarse-grained DP microstructure with discrete martensite islands normally formed in place of pearlitic colonies, which resu...
