    Particles of Zn powder have been studied to show that high-quality scanning electron microscope (SEM) and transmission electron microscope (TEM) specimens can be rapidly produced from a site-specific region on a chosen particle by the focused ion beam (FIB) lift-out technique. A TEM specimen approximately 20-µm long by 5-µm wide was milled to electron transparency extracted from the bulk EBSD of Industrial Materials after Specimen Preparation using Broad Beam Ion Milling. This note illustrates how Broad Beam Ion Milling has been used to produce improved quality of EBSD data from specimen such as aluminium zirconium magnesium titanium alloys and galvanized zinc coatingswhich are usually difficult to prepare by mechanical

    Using the FIB lift-out method we were able to prepare a site-specific TEM specimen from a difficult material in under 3 hours. The TEM analysis of the lift-out specimen revealed a large amount of thin area free from characteristic signs of damage that may be observed as a result of conventional argon ion milling. Optimised milling parameters to minimise these effects are documented but the effect of ion beam imaging during sample preparation is often overlooked. To minimise the sample exposure to the ion beam lift out can be completed normal to the ion beam (tilted relative to the electron beam). This is beneficial for beam sensitive samples as it
