Figure 6
Gauge-volume average X-ray elastic constants ([\bar{s}_{1,hkl}] and [{\textstyle{1\over2}}\,\bar{s}_{2,hkl}]) for the {111} planes of polycrystalline copper for different penetration-depth-to-average-grain-size ratios. Dots correspond to the average data obtained from numerical results for ten different microstructures. The standard deviations are indicated with vertical error bars. The results obtained from equations (26)[link] and (27)[link] are presented with solid lines. The values of bulk X-ray elastic constants, which correspond to an infinite penetration depth, are indicated with dotted lines.
