Mikhail I. Karpov was born in 1944. He graduated from the Physicochemical Faculty of Moscow Institute of Steel and Alloys in 1967 and finished its post-graduate course in 1970. He received his PhD in 1970 and DPhil in 1989. In 1983 he became a State Prize Winner and in 2008 a corresponding member of Russian Academy of Sciences.

M. I. Karpov is an expert on nanostructured metal materials and their fabrication technology. He the author of 114 scientific papers and inventor's certificates.

Main lines of scientific research:

• development of scientific foundation for fabrication of nanostructured metal materials based on techniques of classical metallurgy that allowed to obtain nanostructured composites;
• research of structure and crystallographic texture of mechanical and physical properties of nanostructured materials: M. I. Karpov established the specific plastic behavior of niobium, copper, niobium-titanium alloys б andб  the specifics of the interaction of superconducting vortices with interface surface that can be used as foundation for development of a new generation of structural and functional materials.

Research into the heat- and deformation-induced dislocation structure and crystallographic texture in metals and alloys and their effect on the mechanical and physical properties enabled to develop a novel method of increasing low-temperature plasticity of molybdenum alloy sheets by controlling their crystallographic texture. The new technique of materials processing has been commercially implemented at the Uzbek Plant of Heat-Resistant Metals and Alloys in Chirchik, the Republic of Uzbekistan.

The other type of research resulted in development of a fabrication technology and a new class of materials, namely, multilayer metal composites, nanolaminate materials, composed of tens of thousands of different metal layers with layer thickness down to 2.5 nm. Copper-niobium, copper-iron, niobium-niobium-titanium alloy and other composite nanolaminateб  samples with layer thickness down to 2.5 nm and a total number of layers over 30б 000 were obtained.б  The nanolaminates as a new class of material displayed a number of unique properties. For instance, copper-niobium nanolaminate with a layer thickness of 11 nm had grade 350 HRB and the critical density of supercurrent was by 3 orders of magnitude higher than that in conventional niobium. These achievements enabled current development of new technical nanostructural superconductors and their fabrication technology.

M. I. Karpov is a member of the editorial board of International Journal of Refractory Metals & Hard Materials and associate editor of Deformation and Failure of Materials.
