Characterization of .beta.-phase in Al-Mg-Si alloys by SLEEM and STLEEM techniques
Original language description
Knowledge of the distribution and morphology of the Mg2Si precipitates (i.e. .beta.-phase) in Al-Mg-Si alloys are very important for many practical reasons and the scanning electron microscopy (SEM) technique is widely used for their visualization. Unfortunately, in the standard SEM images these precipitates are barely visible and finding them can be very difficult. Using the cathode lens (CL) mode in the SEM (so called SLEEM) these difficulties have been overcome and a very high contrast between the hexagonal-shaped .beta.-phase and the matrix has been obtained. Moreover, it has been found that the SLEEM images offer the possibility to distinguish between the hexagonal-shaped and the conventional .beta.-phase based on their different brightness, not only on their shape, which can be in some cases difficult or even impossible. Mg2Si precipitates have been also characterized by means of the scanning transmission low energy electron microscopy (STLEEM) method based on the using of a STEM
