The samples were processed by using process parameters as: frequency of torsion (f = 1.6 Hz), compression speed (v = 0.04 mm/s), angle torsion (α = ±6°), height reduction (Δh = 7 mm). The total effective strain was εft = 40. The microstructure has been analyzed by scanning transmission electron microscope (STEM) Hitachi HD-2300A equipped with a cold field emission gun at an accelerating voltage of 200 kV. The quantitative microstructure investigations as disorientation angles were performed using a FEI INSPECT F scanning electron microscope (SEM) equipped with a cold field emission gun and a electron backscattering diffraction (EBSD) detector. The mechanical properties were determined using MST QTest/10 machine equipped with digital image correlation (DIC). The COT processed alloy previously aged at 500°C per 2h shows high mechanical strength, ultimate tensile strength UTS: 521 MPa and yield tensile strength YS: 488 MP attributed to the high density of coherent precipitates and ultrafine grained structure.}, type={Artykuły / Articles}, title={Influence of Solid Solution and Aging Treatment Conditions on the Formation of Ultrafine-Grained Structure of CuCr0.6 Alloy Processed by Compression with Oscillatory Torsion}, URL={http://journals.pan.pl/Content/109184/PDF/AMM-2018-4-65-Urbanczyk.pdf}, doi={10.24425/amm.2018.125143}, keywords={CuCr0.6 alloy, Severe plastic deformation, ultrafine-grains, STEM}, }
