Additive manufacturing of lightweight metals – The process-property relationship
Mustafa Mamduh Mustafa Awd, TU Dortmund, Dortmund, Germany
Development of the layer-wise build-up of metallic materials offered significant technical and economic advantages for modern structural components. The material palette for selective laser melting (SLM) and electron beam melting (EBM) has been expanding to include various Ti and Al alloys as well as steels. On the other hand, process window of additively manufac-tured metallic materials requires careful application since detrimental features to structural strength can develop due to the formation of defects or undesired microstructural features like Si agglomeration in Al-Si alloys. The research strategy covers the scale of properties from sub-grain characterization based on scanning (SEM) and focused ion beam (FIB) microscopy in-cluding mesoscale properties of remnant porosity and binding defects using micro-computed tomography (µ-CT). Finally, macroscale mechanical testing is performed under a wide variety of tactile and non-tactile measurement techniques.
