Description
"Investigations on selective electron beam melting of Ti6Al4V" deals with the influence of process, geometry and scanning parameters during additive manufacturing using an electron beam.
The process parameters are systematically varied to investigate the influence of the energy input during the melting process considering the part´s geometry and the scanning strategy. Therefore, the sample´s density, alloy composition, microstructure and mechanical properties are analyzed. Additional to classical metallographic investigations, process observation with a high speed camera is used to observe the melting process. Numerical simulations support the experimental evaluations and interpretations and provide insight into the extreme occurring melting and solidification process.
The gain in process understanding is used to develop process maps showing parameter fields for the reliable production of parts. Moreover, scanning strategies expanding the process potentials are shown.
