This paper presents a method for precise determination of the orientation of the irrational preferred interface by using TEM. The interface trace and the edge–on orientations are measured careflly and separately to minimize systematic error of thrsults. Tis method was developed according to the error analysis and the fact that te accuracy of the measurement is higher when the measurement is made directly on an interface trace tan on its project on an edge–on orientation, and whn the angle between the trace and the beam direction along the an edge–on orientation is larger. Compard with xisting methods, the present method has minimized the measurement errors and its resuts show better convergence.
Key words： interface orientation; interface trace; Kikuchpaern; edge–on orientation
