The effect of laser focus shift on microstructural variation of Inconel 718 produced by selective laser melting

TL;DR: In this paper, the laser focal shift was used for tailoring the microstructures of parts made by SLM, and the results showed that parts manufactured at different focal positions had finer microstructure than those manufactured away from it.
Journal ArticleDOI

Build Orientation Effects on Texture and Mechanical Properties of Selective Laser Melting Inconel 718

TL;DR: In this article, the variation in tensile properties of Inconel 718 at varying angles with respect to build direction was investigated, and it was found that a preferred grain texture and twinning orientation that aligns with the build direction may contribute to the anisotropic enhancement in ductility.
Journal ArticleDOI

Variations in ambient and elevated temperature mechanical behavior of IN718 manufactured by selective laser melting via process parameter control

TL;DR: In this paper, the effects of process parameters on the microstructural development and mechanical properties of SLM Inconel 718 were investigated using a continuous scanning strategy in conjunction with changes in laser spot size.
Journal ArticleDOI

Formation and evolution of carbonaceous asteroid Ryugu: Direct evidence from returned samples

T. Nakamura, +217 more
- 22 Sep 2022 - 
TL;DR: In this article , the authors analyzed 17 samples of the carbonaceous asteroid Ryugu and found that carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System.
Journal ArticleDOI

Scanning transmission electron microscope mapping of electronic transport in polycrystalline BaTiO3 ceramic capacitors

TL;DR: In this paper, electron beam induced current (EBIC) measurements using a scanning transmission electron microscope have been used for electronic transport mapping in a single dielectric layer of a polycrystalline BaTiO3 multilayer ceramic capacitor (MLCC).
