3D reconstruction for Bravais lattice of unknown crystals using EBSD pattern

A new method to determine unknown lattice of bulk crystals based on electron backscattered diffraction technique has been proposed in the present work.The arithmetic to reconstruct a three-dimensional reciprocal primitive cell in a Kikuchi pattern was introduced in detail.By using overdetermined equations,the parameters of the reciprocal primitive cell were solved according to the information obtained from the width and azimuth of the Kikuchi bands.The results demonstrate that the Bravais lattice type and parameters of unknown crystals could be successfully achieved by means of single electron backscattered diffraction pattern.
