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
Strain rate change tests were performed during low cycle fatigue of polycrystalline copper using plastic strain as the control variable. The evolution of dislocation interactions was observed by evaluating the activation area and true stress as a function of cumulative plastic strain. Activation are
