Figure 7
Bragg edge height of b.c.c. (110) for the five different temperatures (21, 200, 400, 500 and 600°C) by (a) derivative and Gaussian fit of the measured Bragg edge, and (b) values of the theoretical Bragg edge heights based on Fig. 5(c). The distinct shift of the position of the Bragg edge is due to the thermal expansion. |
