Metallographic section of an Aluminium alloy anodized after Barker, micrograph in polarized light.
The purpose of the metallography is to prepare any material in such a way that the microstructure can be analyzed. In our metallographic laboratory, appropriate microsections are prepared for the investigation of microstructure, deformations, cracks or other features of interest.
At the institute, the necessary procedures are maintained at high level, especially for titanium alloys, metal matrix composites and ceramic matrix composites. Furthermore, preparation procedures for new materials are developed or improved. For the accomplishment of these tasks, various cut-off-, grinding machines and mounting presses as well as possibilities for chemical etching are available. As continuous control by light microscopy is necessary during the preparation processes, light-optical microscopic facilities are integrated into the metallographic laboratory.
The various optical equipments enable preparation control as well as elaborated investigations by means of bright- and dark-field microscopy, polarization and DIC methods, imaging with extended depth of focus and laser scanning microscopy (LSM); all with integrated documentation. Besides metallographic courses in cooperation with industrial partners, we also offer support in developing and conducting difficult preparation procedures for external customers.
