SPECIFIC FEATURES OF GRAIN STRUCTURE EVOLUTION IN HPT-NANOSTRUCTURED TIN BRONZE UNDER SUBSEQUENT HEATING

DOI: 10.17804/2410-9908.2019.6.037-047

The grain structure of tin bronze with 7.4 wt% Sn after high-pressure torsion (HPT) at room temperature and subsequent annealing is analyzed. It is demonstrated that, in Cu-7.4%Sn bronze, two groups of grains with different characteristics and different grain-boundary mobility are formed under deformation by HPT. It can be stated that the formation of two groups of grains results from different inclination of grains to relaxation due to the presence of competitive processes occurring directly under deformation. The grains of both groups evolve under heating, with increasing average crystallite size as the annealing temperature rises; however, their volume fraction depends on the defectiveness of the crystallites themselves.

Acknowledgments: The electron microscope investigation was performed on the equipment installed in Nanotechnologies and Advanced Materials Testing Center, IMP UB RAS. The study was performed under the state assignment of from FASO Russia (theme Function, No. AAAA-A19-119012990095-0) and partially supported by the Basic Research Program of UB RAS, project 18–10–2–37.

Keywords: nanostructuring, nanostructures, severe plastic deformation, high-pressure torsion, grain boundaries, thermal stability, tin bronze, statistical analysis
