This laboratory is equipped with testing machines able to perform a great number of mechanical tests, namely tensile, low- and high-cycle fatigue, thermomechanical fatigue, crack propagation, creep and stress relaxation tests up to 1200°C.
Tests are usually performed on samples, according to international standards. In order to meet the requests coming from industrial partners, a system able to stress components with complex geometry was set.
Alloys of interest to industry are tested, such as nickel based superalloys (either polycrystalline or single crystal), intermetallics (TiAl), titanium alloys, oxide-dispersion-strengthened (ODS) alloys, low- and high-alloyed steels, stainless steels, copper alloys. Tests on pure metals, such as copper or nickel, are performed for research purposes.
Materials interesting to industry are usually serviced in the energy area, in particular in power generation (gas turbine, nuclear plants), in aviation or in advanced manufacturing.
