Fig. 1: a) At first, a mechanical pre-preparation is performed using the Leica TXP (cross sectioning) to approach the area of interest in a very short time. b) Then, with the Leica TIC 3X (broad ion milling) a perfect cross-section surface is achieved, which is ready for EBSD analysis.

While the Focused Ion Beam technique is often used for site specific sample preparation, it usually prevents from a successful EBSD analysis by introducing sub-surface deformation and curtaining especially on multiphase material. In this example we have demonstrated that broad ion beam milling allows to simultaneously polish both hard and soft material.
