Deviations from the average lattice parameter, expressed in the form Δa/a, for 40 measurements (top) and 20 pairs (bottom) for the 16MND5 ferritic steel. The average lattice parameter was 2.86772 Å and the standard deviations, expressed as a strain, were 26 and 25 × 10−6, but included a slight difference between collector bank 1 and collector bank 2 as well as a variation through wall of about −40 × 10−6. |
