Evolution of the Structure of Cu–1% Sn Bronze under High Pressure Torsion and Subsequent Annealing

Resumo

The evolution of the structure of tin bronze under the room-temperature high-pressure torsion with different degrees of deformation and the subsequent annealing has been investigated. The thermal stability of the structure formed, namely, its behavior upon annealing in the temperature range of 150–400°C has been studied. The possibility of alloying copper with tin has been analyzed with the purpose of obtaining a thermally stable nanostructure with high strength characteristics.
