Structure and Properties of Ultrafine-Grained Cu-Cr Alloys after High Pressure Torsion

摘要：

The effect of chromium content (0.75,9.85,27%) and initial state on the thermal stability of copper-chromium alloys after severe plastic deformation has been studied by microhardness and electrical resistivity measurements. The stability of the structures is established to depend on the initial state of the alloys and on the content of chromium phase. In the low-alloy bronze, quenching before HPT substantially increases the thermal stability of the alloy relative to that observed after annealing. The softening temperature increases with increasing chromium phase content and reaches 450℃ for the alloy with 27% Cr.
