The Nuclear Unit of IMT had also a set of specific software developed at Oak Ridge National Laboratory (sent by the author Camden R. Hubbard from ORNL, leader of Diffraction and Thermophysical Properties Group): XRAYL (a program for producing idealized powder diffraction line profiles from overlapped powder profiles) and CRYSIZ (a programm for computing crystallite size from the broadening of powder diffraction lines). In IMT, the program CRYSIZ is used to perform the modern Waren Averbach method of X-ray analysis of computing size and strain distributions, especially for the nanostructured materials.
