Metallographic Replica on site tests

Search for structural damage caused by creep.

To investigate the phenomena caused by creep,rectangular plot have been obtained by using portable equipment(polishing disks) in order to obtain the highly polished surfaces. These plots were then attached with appropriate reagents and replicated with sensitive films (replicas of cellulose) in order to obtain an actual copy of the material's metallurgical structure .

The replicated films were observed and evaluated with an optical microscope at 200X 100Xe. To get more magnification it was possible to metallising replica and then observe them with a scanning electron microscope.
