Evaluation of the mechanical properties of Inconel 718 components built by laser cladding
TL;DR: In this article, the mechanical properties of a series of samples built up by laser cladding are evaluated. And the results of tensile tests on various parts show that the laser-cladding strategy has a significant influence on their tensile curves.
Journal ArticleDOI
Post-processing of the Inconel 718 alloy parts fabricated by selective laser melting: Effects of mechanical surface treatments on surface topography, porosity, hardness and residual stress
TL;DR: In this article, the effects of various surface treatments on surface topography, porosity, hardness, and residual stress on turbine blade test parts were studied. And the effect of accumulated energy on the outcomes of the applied surface treatments is also addressed.
Journal ArticleDOI
Modelling of energy attenuation due to powder flow-laser beam interaction during laser cladding process
TL;DR: In this paper, a model based on the shadow created by powder particles on the substrate, with capabilities of estimating the attenuation suffered by the beam and characterizing the density of energy that reaches the surface of the substrate.
Journal ArticleDOI
Evaluation of the relevance of melt pool dynamics in Laser Material Deposition process modeling
TL;DR: In this paper, an analysis of the influence of the melt pool dynamics in a LMD model and its impact on the accuracy is presented, and an exponential formula based on the response surface methodology (RSM) is obtained.
Journal ArticleDOI
