The cyclic deformation of Ni[1 10] single crystals has been investigated in tension-compression under total strain control. The slip systems found by slip trace analysis are (101)[11 i], (112)[11 i] and (213)[ 11 i]. Transmission electron microscopy (TEM) observations showed that at the saturation s
Cyclic deformation behavior of double-slip oriented Cu single crystals with a stress axis in the [034] direction was investigated under plastic strain control mode for a shear strain amplitude range of 1 x 10-4 to 5 x 10-3. Dislocation structures in the tested samples were observed using a transmiss
During cyclic deJormation of nickel single crystals at 78 K, a wall-like structure develops up to the saturation stage over the entire specimen volume. Nevertheless, the observation of persistent slip markings on the surface indicates that the plastic deformation is non-homogeneous. A more detailed
