SHELEG Valery Konstantinovich

Valery Konstantinovich Sheleg (b. 26.04.1946, Minsk) - a scientist in the field of engineering technology, including powder metallurgy, materials science, welding and protective coatings. Corresponding Member (2014), Doctor of Engineering Sciences (1989), Professor (1991). Honored Scientist of the Republic of Belarus (2001).

Works in the field of theory and practice of creating porous powder materials and products from them for various purposes. Developed important issues of the theory of obtaining structures with a uniform distribution of pores in size over the area of ​​the filtering partition, control of the characteristics of the porous structure of effective capillary-porous powder materials, characterized in the process of operation by the transport of fluid into them under the action of capillary forces. Established patterns of changes in the structure and properties of porous powder materials in the process of free precipitation, creating biporous, multilayer structures and continuously changing pore sizes, as well as obtaining products from refractory metal powders (titanium, niobium, tantalum) by the method of electropulse sintering, highly porous cellular materials based on Ni–Cr–Al system alloys and ceramics - of alumina. Developed new methods for controlling their properties and a number of technological processes for obtaining such materials, as well as equipment, technological equipment and organized industrial production at the Molodechno Powder Metallurgy Plant.

Author of more than 680 scientific papers, including 19 monographs, about 270 copyright certificates and patents.

Lenin Komsomol Prize of Belarus (1978) for research and development of new heat exchangers with capillary structures and their introduction into industry. State Prize of the BSSR (1980) for the development and introduction into the national economy of new porous materials and products based on metal powders. Prize of the Council of Ministers of the USSR (1987) for the development and introduction of permeable materials with high performance properties into the national economy. Prize of the National Academy of Sciences of Belarus (1997) for the monograph “Theory and practice of electropulse sintering of porous powder materials”.
