Figure 5
Calculated and measured wavelength-dependent attenuation coefficients. (a) Measurements at 21, 200, 400, 500 and 600°C. (b) Measurements at 600 and 700°C revealing the progression of the phase transformation from b.c.c. to f.c.c. at 700°C. (c) Values calculated using the software nxsPlotter for the single b.c.c. phase. (d) Comparison between experimental data measured at 21 and 600°C, taken from (a), and the corresponding calculated values given in (c). The calculated data were smeared by convolution with the wavelength resolution function of the double-crystal monochromator. |
