The Center develops technological processes for synthesizing parts from alloys of various compositions using laser 3D printing methods — selective laser melting (SLM) and direct laser growth (DLG).

RESOURCES

The laboratory facilities allow us to carry out the following research methods:

• metallographic analysis of the structure of metals and alloys;
• X-ray diffraction analysis of metals and alloys, including determining phase composition, crystal parameters, texture and macrostresses;
