A data analysis system has been developed to determine texture, lattice strain, block (or grain) size and dislocation density from neutron diffraction profiles obtained by an angular dispersive method. The texture is evaluated from the integrated area of the curve-fitted quasi Voigt function for experimental profiles. The block size and dislocation density are obtained by profile analyses based on an integral breadth method as well as a Fourier coefficient method. The obtained results of lattice strain, block size and dislocation density are superposed onto the orientation pole figure as output results. The developed system was applied to a cold-rolled SUS316 steel and drawn carbon steel wires to examine its usefulness.
