Effect of heat treatment on the microstructure and mechanical properties of Inconel 718 processed by selective laser melting
TL;DR: The microstructural and mechanical properties of Inconel 718 were determined on the specimens manufactured by selective laser melting (SLM) of prealloyed powder as mentioned in this paper, showing that columnar grains of supersaturated solid solution with internal microsegregation of Nb and Mo, demonstrated by fractions of Laves eutectic or its divorced form in interdendritic regions.
Journal ArticleDOI
Microstructure and mechanical behaviour of Ti―6Al―7Nb alloy produced by selective laser melting
TL;DR: In this article, the influence of the SLM manufacturing strategy on mechanical properties and microstructure of the as-built Ti-6Al-7Nb alloy was determined by tensile and compression testing.
Journal ArticleDOI
Correlation between process parameters, microstructure and properties of 316 L stainless steel processed by selective laser melting
TL;DR: In this paper, high-density 316 L specimens were fabricated by selective laser melting (SLM) and different processing parameters, including laser power (100, 200 W) and scanning strategies (alternating stripes without and with remelting after every layer) were employed to evaluate their impact on microstructure and texture of the specimens.
Journal ArticleDOI
Laser powder bed fusion of AA7075 alloy: Influence of process parameters on porosity and hot cracking
TL;DR: In this paper, the authors investigated the relationship between laser powder bed fusion (LPBF) parameters and defect formation with a focus on hot cracking and discussed the process window for the LPBF manufacturing of defect-free components of AA7075 alloy.
Proceedings ArticleDOI
Parameters in selective laser melting for processing metallic powders
TL;DR: In this article, the authors present results of selected variable parameters (laser power, scanning time, scanning strategy) and fixed parameters such as the protective atmosphere (argon, nitrogen, helium), temperature, type and shape of the powder material.
