Phenomena of physics taking place during hardening steel in water salt solutions of optimal concentration

Nikolai I Kobasko

In the paper the idea on forced heat transfer exchange is discussed and used for designing the new quenching technology which is less costly and can be implemented as a mass production in the heat treating industry. The new technology explores optimal hardenability steel resulting in creation surface compressive residual stresses followed by super strengthening effect that saves alloy elements and increases service life of products. It is shown that optimal quenched layer in steel can be achieved if cooling is interrupted at proper time. For this purpose a generalized equation is used and examples of calculations are provided. If mass production of new technology is achieved, it can reduce emission of CO2 into atmosphere since long lasting and costly carburization processes can be eliminated via using optimal hardenability steels. The proposed new technology can be combined with exploring hydrodynamic emitters that produce resonance effect to destroy film boiling process. Obtained results are useful for the practice and are interesting for persons who are going to investigate carefully the unusual phenomenon on forced heat transfer exchange.
