Project summaryRecent studies convincingly demonstrated a high potential of severe plastic deformation (SPD) methods for fabricating nanostructured ultrafine-grained states in various metals and alloys. Formation of nanostructures is the basis of cardinal changes in materials properties and attaining such advanced characteristics as very high strength with a sufficient ductility, high fatigue strength and life, wear resistance, superplasticity and others.
The present project aims to process large-size bulk nanostructured samples and billets (40 mm in diameter, 200 mm in length) and treat hard-to-deform low-ductile materials, such as intermetallics, from a number of pattern and commercial alloys by developing severe plastic deformation techniques. The problems of processing homogeneous nanostructures required for stable properties in billets will be solved. Using this basis the advanced metallic alloys and intermetallics will be attained, in particular:
– nanostructured Al and Ti alloys, low-carbon steels with unique superplastic properties at elevated temperatures and high strength at room temperature;
– nanostructured Ni-Ti, Ni-Al intermetallics demonstrating unique strength and ductility combinations;
– nanostructured magnet Fe-Nb-B materials for permanent magnets with a record coercitive force. Pilot samples will be produced and bench tests will be carried out;
– nanostructured Cu for coating jet charges for perforation of oil and gas wells.
Among the project participants there will be experts from RFNC-VNIIEF (Sarov), Ufa scientists, who are pioneers in application of severe plastic deformation techniques and fabrication of nanostructures; experts from Tomsk responsible for the mechanical tests and structural modelling; specialists from Moscow, who will provide structural characterization of the processed materials. Experts from Sarov will be responsible for a range of articles made from nanostructured materials, bench tests, fabrication of SPD-equipment. The foreign co-executives are experts from Los Alamos National Laboratory (USA) and Franhofer Institute fur Angewandte Materialforschung (Dresden, Germany). They will evaluate the quality of the new materials.
The project duration is proposed for 2 years.
The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.
ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
