Maxim Murashkin graduated from Ufa State Aviation Technical University (Ufa, Russia) in 1993 with the speciality of Machines and Metal Forming Technology. From 1993 until 2003 he worked at the Institute for Metals Superplasticity Problems of the Russian Academy of Sciences (IMSP RAS). In 2002 he defended his PhD thesis on the topic: «Structure and mechanical properties of commercial Al alloys 1560 and 5083 of the Al-Mg-Mn system processed by severe plastic deformation» in the speciality of Materials Science (Machine Building) at IMSP RAS.

Since 2003 Maxim Murashkin has been working at IMPAM USATU (initially as researcher, and since 2011 as senior researher).

At present the main area of his research activities is the development of the principles for enhancement of mechanical and performance properties of Al alloys for structural and electrical engineering applications, using severe plastic deformation.

The total number of his publications in Russian and international journals and conference proceedings is over 170.

Since 2016 he has published 69 papers, including 38 in journals indexed by Web of Science. In the past 5 years he has authored 5 patents and 3 monographs.

The main areas of research activities of the grop headed by Maxim Murashkin include:

• Al-based conductor materials with enhanced strength, electrical conductivity and heat resistance (chemical compositions, thermomechanical treatment (TMT) regimes, SPD processing);

• Principles of designing regulated/gradient nanostructures in Al alloys for electrical-engineering or structural applications, using TMT, including that with the use of SPD;

• Microstructure analysis of Al alloys by optical microscopy, electron microscopy and X-ray structural analysis, and measurement of functional properties (electrical conductivity, static and cyclic strength, heat resistance, corrosion resistance, and corrosion protection methods);

• Nanostructurted Al alloys produced by new methods of powder metallurgy combined with SPD processing: structural features, physical and mechanical properties, innovation potential.

His h-index in journals indexed by Web of Science is 26, and in those indexed by Scopus – 29.
