Selective laser beam melting of composite material for lightweight structures (A05)

• Subject Area: Production Automation and Assembly Technology
• Term: from 2011 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 61375930

This sub-project investigates the processing of alloys of the EN AW-6xxx group using laser beam melting into parts. This requires a fundamental understanding and control of the solidification conditions. Using spectroscopy and hyperspectral imaging, the real temperatures are measured, spatially and temporally resolved. Using diffractive beam forming of the laser beam intensity profile, the temperatures and thus the solidification conditions are controlled. Furthermore, the influence of nucleating agents is investigated and the microstructure is adjusted in a defined manner.
