Lightweight intermetallic γ-TiAl based alloys are innovative high-temperature structural materials. So far, these in use as turbine blades or turbocharger wheels advanced aerospace and automotive engines, where they produced by means of investment casting well wrought processing, e.g. hot-forging. Through the development powder-based additive manufacturing processes within last decade, a real paradigm shift for future component production their design materials properties was created. While...
The development of process parameters for electron beam powder bed fusion (PBF-EB) is usually made with simple geometries and uniform scan lengths. transfer to complex parts various lengths can be achieved by adapting such as power speed. Under ideal conditions, this adaption results in a constant energy input into the despite local length. However, numerous PBF-EB machines show deviations from situation because diameter subject significant changes if changed. This study aims demonstrate...
Electron Beam Powder Bed Fusion (PBF-EB) is an Additive Manufacturing (AM) method that utilizes electron beam to melt and consolidate metal powder. The beam, combined with a backscattered detector, enables advanced process monitoring, termed Optical Imaging (ELO). ELO already known provide great topographical information, but its capabilities regarding material contrast are less studied. In this article the extents of using investigated, focusing mainly on identifying powder contamination....
Abstract Electron beam powder bed fusion (PBF-EB) is an additive manufacturing (AM) technology that maturing toward broader industrial applications. However, conventional PBF-EB machines are still limited to 60 kV acceleration voltage (U b ). Therefore, this work presents the first results of a novel prototype machine capable voltages up 150 kV. In general, higher enables larger powers, which shortens pre-heating time and makes area available. Moreover, lower current required for same power...
The dual microstructure concept for gamma titanium aluminides (γ-TiAl) processed via electron beam–powder bed fusion (PBF-EB) provides a huge potential more efficient jet turbine engines. While the is feasible and mechanical properties are promising, there still some challenges. For an industrial application, heat treatment window has to match conditions in furnaces. This study shows how required can be achieved advanced PBF-EB technology. Through using beam with 150 kV acceleration voltage,...
