Leibniz-IWT offers comprehensive expertise in the material-specific processing and targeted modification of metallic materials. The aim is to adjust defined microstructures and properties using thermal, thermomechanical, and hybrid processes.
Our services address both conventionally and additively manufactured materials and enable adaptation to specific functional and structural requirements.
