Figure 5
Diffraction and mechanical Young's moduli of Cu and CrN films with 111 fibre texture, shown as a function of the sample tilt angle ψ. The moduli were calculated using the ODF from Fig. 2 supposing the Hill (1952) grain-interaction model. The diffraction moduli represent the elastic response of diffracting grains and the mechanical moduli represent the elastic response of all crystallites in the film. The moduli are expressed as a function of the tilt angle ψ, which defines also the orientation of the diffraction vector (Fig. 1). |
