Biography : Professor Gorkunov, Eduard Stepanovich, started his research activity in the post-graduate school at the Urals State University under the supervision of Professor Mikheyev, Corresponding Member of the Russian Academy of Sciences, in 1970. On receiving his Candidate degree (Physics and Mathematics) at the Urals State University in 1977, Gorkunov joined the staff of the Institute of Physics and Technology, Russian Academy of Sciences (Urals Branch), Izhevsk, Russia, as a senior research associate and later was appointed Head of Laboratory and Deputy Director for Research Activity. In 1987 he returned to Ekaterinburg to head the Nondestructive Testing Laboratory at the Institute of Physics of Metals, Russian Academy of Sciences (Urals Branch).
Having become Doctor of Science (Technology) in 1988, E. S. Gorkunov was appointed Deputy Director for Research Activity at the Institute of Physics of Metals, Russian Academy of Sciences (Urals Branch), Ekaterinburg. Since 1994 Professor Gorkunov has been Director of the Institute of Engineering Science, Russian Academy of Sciences (Urals Branch), Ekaterinburg. In 1997 he was elected Corresponding Member of the Russian Academy of Sciences.
At present Professor Gorkunov is holding numerous administrative posts, namely, Vice-President of the Urals Branch of the Russian Academy of Sciences (since 1995), Director of the Institute of Engineering Science (since 1994), Vice-President of the Scientific Council for Nondestructive Methods of Physical Testing at the Russian Academy of Sciences, Vice-President of the Russian Society for Nondestructive Testing and Technical Diagnostics, Deputy Editor-in-Chief of the Russian Journal of Nondestructive Testing, member of the Editorial Board of the journals Testing. Diagnostics and Mechanical Engineering and Education of Engineers, member of the Bureau of the United Council for Mathematics and Mechanics at Presidium of the Urals Branch of the Russian Academy of Sciences, member of the Russian National Certification Committee for Nondestructive Testing.
Professor Gorkunov spends much time working with undergraduate and postgraduate students, competitors for degrees. He used to lecture at Tyumen Industrial Institute, Udmurt State University and Izhevsk Mechanical Institute. He now heads a chair and lectures on special courses of Nondestructive Physical Testing Techniques at the Urals State Technical University (USTU-UPI). Among his disciples there are 2 Doctors of Science and 11 Candidates (approximately equals to Ph.D.).
The research efforts are concentrated on the development and design of magnetic and electromagnetic techniques and equipment for technical diagnostics of critical machines and structures, as well as for predicting their service life.
The scientific activity is focused on fundamental investigations into magnetization reversal, magnetic properties and their correlation with structure, composition and strength characteristics of materials in an effort to evaluate physical and mechanical characteristics and to inspect the quality of rolled products and machine parts.
Magnetic phase-structural analysis as an effective tool for inspecting the quality of materials has made it possible to correlate magnetic properties with phase and structural transformations in ferromagnetic steels and alloys during various strengthening treatments. To achieve this goal, general mechanisms of changes in magneto-elastic, magneto-elastic-acoustic, electric and mechanical properties of steels under various conditions of strengthening treatment (bulk and surface heat treatment) were thoroughly examined and classified.
Scientific background has been developed for structural inspection of steel products and for technical diagnostics of structural components by means of the analysis of the insensitivity of magnetic states to the influence of applied electromagnetic field, elastic strains and temperature.
Both well-known and newly revealed physical phenomena, such as electromagnetic-acoustic transformation, magneto-elastic-acoustic emission and piezodynamic magnetization, have been involved for inspecting macro- and microstresses and for evaluating plastic strain rate. Special emphasis has been laid on the research and development of the theoretical basis and design of engineering systems for electromagnetic inspection of such critical engineering characteristics of materials as abrasive wear resistance of high-carbon steel products and cutability of hard-alloy cutting tools. A method for inspecting the wear of sliding tribo-interfaces by means of eddy-current technique was developed. The detailed analysis of the dimensions and magnetic properties of wear particles localized in lubricants has made it possible to predict the lifetime of sliding tribo-interfaces.
The unique data obtained on the correlation between the magnetic properties of major structural steel and cast iron grades and their structural-phase state were published in 8 monographs, 19 surveys and 31 patents, and they are currently used at a number of metallurgical and machine-building plants in Russia and other countries of the former USSR. Calculation algorithms for primary transducers were developed in order to provide facilities for conducting nondestructive inspection at various industrial enterprises. Numerous techniques and engineering systems for technical diagnostics and nondestructive testing were designed and implemented in the following areas:
- estimation of the structural state and mechanical properties of cold
- and hot-rolled products;
- inspection of the structural state and strength of steel and cast-iron products after bulk heat treatment - annealing, normalization, quenching, tempering and ageing;
- testing of the phase composition and porosity, detection of paramagnetic and ferromagnetic areas with specific physical properties in cast cermet products and in welded joints;
- estimation of the stress state in materials and structures after heat treatment and plastic deformation, as well as in use;
- detection of structure degradation and inspection of changes in mechanical properties caused by external effects;
- inspection of the structure, physical-mechanical properties and layer thickness of metal products after various surface treatments
- induction hardening, thermochemical treatment, strengthening by high energy flux, vibration hardening, decarburization of steel and chilling of cast iron;
- grading of steel products and qualitative estimation of their chemical composition.

Eduard S. Gorkunov is Corresponding Member of the Russian Academy of Sciences, Honorary Fellow of the Bulgarian NDT Society. He is awarded by the Order of Friendship, the State's Prize of the Russian Federation in Science and Technology, the RF Government's Prize.
