BIME/NTU 工材作業二
1. Figure 3.20 shows an x-ray diffraction pattern for α-iron taken using a
diffractometer and monochromatic x-radiation having a wavelength of 0.1542 nm;
each diffraction peak on the pattern has been indexed. Compute the interplanar
spacing for each set of planes indexed; also determine the lattice parameter of Fe for
each of the peaks.
2. The diffraction peaks shown in Figure 3.20 are indexed according to the reflection
rules for BCC (i.e., the sum h+ k+ l must be even). Cite the h, k, and l indices for the
first four diffraction peaks for FCC crystals consistent with h, k, and l all being
either odd or even.
3. Text book problem 3-77
