Microstructural parameters from X-ray diffraction peak broadening

X-ray diffraction peak profiles provide crystallite size, size distribution and dislocation structure. Theoretical size and strain profile functions are given by the minimum number of parameters required by physics and are compared with TEM results. Strain anisotropy gives information about dislocation character and Burgers vector populations. Thermal stability determined by X-rays and calorimetry is discussed for recovery.
