5 Conclusions 1) Detailed and practical parameters of the electropolishing, silica polishing and ion milling have been summarized. Ion milling is a real universal and promising polishing method for EBSD preparation of almost all materials. 2) There exists a maximum value of indexed points as a function of step size. The optimum step size depends on the magnification and the board resolution/electronic step size. 3) Grains/subgrains and texture, and grain boundary structure are readily obtained by EBSD. 4) Strain and stored energy may be analyzed by EBSD
