Journal ArticleDOI
On the role of melt flow into the surface structure and porosity development during selective laser melting
Chunlei Qiu,Chinnapat Panwisawas,Mark Ward,Hector Basoalto,Jeffery Brooks,Moataz M. Attallah +5 more
TL;DR: In this paper, the development of surface structure and porosity of Ti-6Al-4V samples fabricated by selective laser melting under different laser scanning speeds and powder layer thicknesses has been studied and correlated with the melt flow behavior through both experimental and modelling approaches.
Journal ArticleDOI
Influence of processing conditions on strut structure and compressive properties of cellular lattice structures fabricated by selective laser melting
Chunlei Qiu,Sheng Yue,Sheng Yue,Nicholas J.E. Adkins,Mark Ward,Hany Hassanin,Peter D. Lee,Peter D. Lee,Philip J. Withers,Moataz M. Attallah +9 more
TL;DR: In this article, the as-fabricated strut size, morphology and internal porosity were investigated using optical microscopy, scanning electron microscopy (SEM) and X-ray microtomography (micro-CT) and correlated to the compressive properties of the structure.
Journal ArticleDOI
A Multiscale 3D Model of the Vacuum Arc Remelting Process
TL;DR: In this article, a three-dimensional, transient, multiscale model of the VAR process is presented, allowing novel simulations of the influence of fluctuations in arc behavior on the flow and heat transfer in the molten pool and the effect this has on the microstructure and defects.
