Paradox Kobasko as Green Avenue for Design Super Strong Materials

Abstract

In the paper the three principles of transient nucleate boiling are used to explain why during quenching in cold fluid, performed under increasing pressure, very important for the practice paradox takes place. Its essence consists in simultaneously increase surface temperature and quick decrease core temperature of quenched steel part when heat transfer coefficient tends to infinity. The discovered paradox can be explored for designing super strong bainite via intense quenching combined with the low and high temperature thermomechanical treatment. The paradox is observed when quench tank is hermitized, the probe is immersed into quenchant and pressure is immediately increased. The two generalized fundamental equations related to transient nucleate boiling and convection create the basis for designing software that governs intensive quenching (IQ) process and bainitic transformations. The schematic installations for quenching samples in cold fluid under pressure is discussed in the paper. Example of calculation is provided. The article can be used by students, engineers, professors and just by good people who are interested in achievements of physics.
