Change of Parameters of the Koiwa–Hasiguti Dynamic Dislocation Relaxation in Nanostructured and Polycrystalline Zirconium after Severe Plastic Deformation and Annealing

Figure 7

Dependences on the parameter β of (a) the height of the relaxation component of the KH peak (the solid line is the approximation by (27)), (b) the ratios K of the derivatives at the inflection points on the left and right sides of the KH peak (30), and (c) the area under the peak. Filled symbols refer to the KH peak; open symbols refer to the Debye peak.
