Professor: Keith Stevenson

 

Dr. Shakhova’s research focuses on grain refinement process and regularities of microstructure evolution of metallic materials, especially austenitic stainless steel, copper and copper-based alloy, during large plastic deformation, relationship between microstructure and mechanical properties and development of new type of coatings for automobile industries.

Dr. Shakhova’s recieved her MS/BS in Materials Science and Engineering (Applied Material Science) in 2010 from Faculty of Mechanics and Engineering, National Technical University «Kharkov Polytechnical Institute», Kharkov, Ukraine. From 2010 to 2016, she worked in Laboratory of Mechanical Properties of Nanoscale Materials and Superalloys, Belgorod State University, Belgorod, Russia. The main attention during work in Laboratory of Mechanical Properties of Nanoscale Materials and Superalloys was paid to studying of staging of submicro – and nanocrystalline structure formation, via microstructure characterization, under condition of large plastic working.

Dr. Shakhova defended her Ph.D. titled “Regularities of microstructure evolution in austenitic stainless steel S304H during large cold rolling and subsequent annealing” at 2013 in National University of Science and Technology “MISIS”, Moscow, Russia. During her Ph.D. studentship she guided 2 students on graduate level.

She authored 10 papers in per-reviewed international journals, 8 conference papers published in Materials Science Forum and Advanced Materials Research and 2 patents.

 

Evaluation of microstructural and mechanical properties of advanced materials developed by additive manufacturing technology.

Development of new wear resistance coatings for cylinders block.

Cylinders block of automobile engine undergoes intensive loads during exploitation. It is well known that the most important characteristic for cylinders block is resistant to different types of wear. First cylinders blocks were made from cast iron, but in order to made lighter cylinders block during last decades aluminum alloys are most interesting candidates for manufacturing cylinders block. Note here that aluminum alloys have low wear resistance. From this point of view it is interesting to develop new wear-resistant coatings for aluminum alloys used in the automotive industry.  As was mentioned above wear resistance coatings are necessary for aluminum alloys used in the automotive industry. New high entropy alloys developed during last few decades are of promising candidates for wear resistance coatings, since these alloy shows a high mechanical properties (hardness, tensile strength and so on), functional properties (wear resistance) and etc. As a method of coating deposition may be used thermal spaying, magnetron sputtering and etc.
