Abstract: The nucleate boiling processes are in use in everyday people’s activity; and they were carefully investigated mainly for steady state condition. The transient nucleate boiling processes take place during quenching of steels and metal alloys; and they were investigated not enough deeply yet. During last decades the new characteristics of the transient nucleate boiling process were discovered which can be formulated as follows. The duration of the transient nucleate boiling process is directly proportional to squared size of a component and inversely proportional to thermal diffusivity of a given material, depends on configuration of component, initial temperature and thermal properties of liquid. The surface temperature of a component during the nucleate boiling process is maintained at the level of boiling point of liquid until heat flux densities during nucleate boiling and convection become equal. These characteristics were widely discussed at the WSEAS Conferences. In present lecture, it is further discussed the possibility of use of the discovered characteristics in the heat treating industry. Namely, they can be used for testing of materials and new intensive technologies development.

The first includes:
• Evaluation of the thermal diffusivity of different kinds of solid materials.
• Explanation what Grossmann factor H is.
• Development of the new method for testing of different kinds of quenchants.
• Criteria to be used for simplified calculations and designing of technological systems.
• Opportunities for materials savings and environment improvement.

The second includes:
• Optimizing technological IQ – 2 processes.
• Extended possibility of the low temperature thermo-mechanical heat treatment (LTMT).
• Modifying of the cryogenic treatment of materials.
• Optimizing of the continuous casting process for receiving nano – particles after intensive cooling.
• Condition for super strengthening of steels.
• Reduced cost of the technological process.
• Monitoring of the process of phase transformation and residual stress distribution.
These aspects will be discussed at the WSEAS Conference with the aim of saving expensive materials and improving environment condition.

Brief Biography of the Speaker:
Dr. Kobasko received his Ph.D. from the National Academy of Sciences of Ukraine. He is a leading expert on quenching and heat transfer during the hardening of steels. He was the Head of the laboratory of the Thermal Science Institute of the National Academy of Sciences of Ukraine. He is Director of Technology and Research and Development for IQ Technologies, Inc., Akron, Ohio and supervisor of Intensive Technologies, Ltd, Kyiv, Ukraine. The aim of both companies is material savings, ecological problem-solving, and increasing service life of steel parts. He is an ASM International Fellow (FASM). Dr. Kobasko is the author and co-author of more than 250 scientific and technical papers, several books and more than 30 patents and certificates. He received the Da Vinci Diamond Award and Certificate in recognition of an outstanding contribution to thermal science. Dr. Nikolai Kobasko was Editor-in-Chief and Co-Editor of the WSEAS Transactions on Heat and Mass Transfer; and is currently a member of the Editorial Board for the International Journal of Mechanics (NAUN) and the Journal of ASTM International (JAI). The new characteristics of transient nucleate boiling processes were discovered by him. These characteristics are basics for new technologies development and new method of testing materials which are discussed in the lecture.
