additive manufactured alsi10mg samples using selective laser melting slm microstructure high cycle fatigue and fracture behavior
Materials & Design, 2012Co-Authors: Erhard Brandl, Ulrike Heckenberger, Vitus Holzinger, Damien BuchbinderAbstract:Abstract In order to produce serial parts via additive layer manufacturing, the fatigue performance can be a critical attribute. In this paper, the microstructure, high cycle fatigue (HCF), and fracture behavior of additive manufactured AlSi10Mg samples are investigated. The samples were manufactured by a particular powder-bed process called Selective Laser Melting (SLM) and machined afterwards. 91 samples were manufactured without (30 °C) and with heating (300 °C) of the Building Platform and in different directions (0°, 45°, 90°). Samples were tested in the peak-hardened (T6) and as-built condition. The Wohler curves were interpolated by a Weibull distribution. The results were analysed statistically by design of experiments, correlation analysis, and marginal means plots. The investigations show that the post heat treatment has the most considerable effect and the Building direction has the least considerable effect on the fatigue resistance. The fatigue resistance of the samples, however, is high in comparison to the standard DIN EN 1706. The combination of 300 °C Platform heating and peak-hardening is a valuable approach to increase the fatigue resistance and neutralize the differences in fatigue life for the 0°, 45°, and 90° directions.

Electropolishing and electropolishing-related allowances for powder bed selectively laser-melted Ti-6Al-4V alloy components
Journal of Materials Processing Technology, 2017Co-Authors: V. Urlea, Vladimir BrailovskiAbstract:This study allowed the current density optimization for the efficient electropolishing of Ti-6Al-4V test coupons containing multiple surfaces, which were oriented with respect to the Building Platform under angles varying from 0 to 135°. It was shown that despite a large scatter in the as-built surface finish, ranging from Ra = 4 μm (0°) to Ra = 23 μm (135°), all the differently-oriented surfaces were polished down to a uniform roughness of Ra = 1–3 μm. This means that the higher the as-built surface roughness, the larger the quantity of the material needed to be removed during electropolishing in order to reach a uniform level of surface finish. Finally, thickness evolution measurements during finishing of the differently-oriented test coupons allowed us to establish the build orientation-dependent allowances for the electropolishing of selectively laser-melted Ti-6Al-4V parts.
