Process optimisation of selective laser melting using energy density model for nickel based superalloys (2016, background): “Previous works presented by Carter et al.5,6 have examined process optimisation of SLM for high c9 volume fraction alloys and associated microstructural inhomogeneity induced by the laser scanning strategy.7 There has been significant focus on the alloy IN718 due to its weldability typified by the s”
Review on powder-bed laser additive manufacturing of Inconel 718 parts (2015, background): “Second, it has excellent oxidation resistance and hot corrosion resistance [34-36], which has favored its use at a high temperature up to 700 °C and the atmosphere where is highly carburizing and oxidizing, such as combustion chambers, turbine blades, and nuclear reactors, components for rings, airc”
Parametric analysis of thermal behavior during selective laser melting additive manufacturing of aluminum alloy powder (2014, unknown): “During the SLM process, the heat is mainly dissipated through the previously fabricated layer [37].”
Computational modeling of residual stress formation during the electron beam melting process for Inconel 718 (2015, unknown): “[14] Other work has calculated geometric deformation in LM parts, demonstrating the usefulness of using FEA tools for studying AM processes [24].”
