...N. I. Kobasko; A. A. Moskalenko; V. V. Dobryvechir; L. M. Protsenko In this paper, a method of intensive quenching in water salt solutions, known as the IQ-2 process, is considered. To realize the IQ-2 process, water salt solutions were used, including with NaNO 3 , Na 2 CO 3, NaCl, CaCl 2 , MgCl 2...

.... Calculation results coincide with each other, which indicates that the generalized equation is a suitable method for calculations and development of intensive quenching technologies. As an example, the processes for quenching semiaxle and cylindrical forgings are considered. CFD analysis successfully detected...

...N. I. Kobasko; M. A. Aronov; J. A. Powell; G. E. Totten Three intensive quenching processes known as IQ-1, IQ-2, and IQ-3 are considered. In contrast to IQ-2 and IQ-3, processes that use water as a quenchant, the two-step IQ-1 technique is actually a combination of a conventional quench (in oil...

...Nikolai I. Kobasko Low and limited hardenability (LH) steels are plain carbon steels characterized by a low content of alloying elements (Cr, Ni, Mo, W, V, etc.). The use of LH steels with an intensive quenching method allows full elimination of the carburization process for a variety of steel...
