The popLA (preferred orientation package - Los Alamos) texture analysis software package, developed at Los Alamos by Fred Kocks and collaborators, provides a comprehensive treatment of material texture analysis by reducing, visualizing and discetrtizing texture data in a flexible format. The distribution of crystal orientation, or texture, in polycrystalline materials is calculated and displayed by a wide variety of graphic formats for comparison with published results. Once distributions have been determined, standard methods can be used to predict mechanical properties employed by industry to design and control efficient metals and ceramics processing techniques. ..
