The cracking of materials and fracture surface is metal-chastity of great practical and academic importance.Over the last few years the development of the fractography of crystalline alloys resulted in a useful tool for the prediction or failure analysis.Many attempts have been made to observe cracks using optical microscopy, X-ray topography and transmission electron microscopy (TEM).Of these techniques, the resolution of optical microscopy and X-ray topography is too poor.By contrast, the resolution of TEM is high enough for detailed information to be obtained.

However, in order to apply TEM observations, a thin foil specimen must be prepared, and it is usually extremely difficult to prepare Liebherr CUEL2831 55cm Fridge Freezer – SILVER 265 litres A++ such a specimen from a pre-selected region containing a crack.
