Effect of strain rate on deformation texture in OFHC copper
A strong strain rate dependence on the crystallographic texture of oxygen-free high conductivity copper is observed and reported for the first time. Two shear compression specimens were deformed at widely different strain rates (0.001 s 1 and 7000 s ) to the same strain, and their textures were determined using orientation image microscopy. By comparing the stress–strain curves and the major te...
متن کاملEvolution of Texture and Grain Size during Equal Channel Angular Extrusion of Pure Copper and 6012 Aluminum
Among different SPD techniques, Equal channel Angular Pressing has attracted the most attentions, because of applying large strain to solid bulk materials. In this research, ECAP process up to 6 passes was carried out on a pure copper and a 6012 Al-Mg-Si alloy with BC route in ECAP dies with Φ=120 and Ψ=20 and diameter of 20and 10 millimeter respectively. Moreover, X-ray diffraction (XRD) syste...

متن کاملMicrostructure Evolution during Tensile Deformation of a Nanostructured Bainitic Steel
In situ neutron diffraction experiment was used during tensile testing at room temperature to examine the changes on the percentage and texture of both ferrite and austenite in a nanocrystalline bainitic steels transformed at two different temperatures 200°C and 300oC for different times to achieve the same phase percentages. Both samples showed an inadequate capability of austenite to transfor...
