Modulating laser intensity profile ellipticity for microstructural control during metal additive manufacturing
Tien T. Roehling,Tien T. Roehling,Sheldon Wu,Saad A. Khairallah,John D. Roehling,S. Stefan Soezeri,Michael F. Crumb,Manyalibo J. Matthews +7 more
TL;DR: In this paper, the effects of laser intensity profile ellipticity on melt track macrostructures and microstructures were studied in 316L stainless steel, and the results were supported by temperature gradients and melt velocities simulated using the ALE3D multi-physics code.

A cellular automaton finite volume method for microstructure evolution during additive manufacturing
TL;DR: In this article, a 3D cellular automaton method is coupled with a finite volume method to predict the grain structure of an alloy, e.g. Inconel 718, fabricated by additive manufacturing.

Contraction of aluminum alloys during and after solidification
TL;DR: In this paper, a technique for measuring the linear contraction during and after solidification of aluminum alloys was improved and used for examination of binary and commercial alloys, and the effect of experimental parameters, eg., the length of the mold and the melt level on the contraction was studied.

Hot tearing susceptibility of binary Mg–Y alloy castings
Zhi Wang,Zhi Wang,Yuanding Huang,Amirthalingam Srinivasan,Zheng Liu,Felix Beckmann,Karl Ulrich Kainer,Norbert Hort +7 more
TL;DR: In this article, the influence of Y content on the hot tearing susceptibility of binary Mg-Y alloys has been predicted using thermodynamic calculations based on the Clyne and Davies model.

High-frequency periodic patterns driven by non-radiative fields coupled with Marangoni convection instabilities on laser-excited metal surfaces
Anton Rudenko,A. Abou-Saleh,Florent Pigeon,Cyril Mauclair,Florence Garrelie,Razvan Stoian,Jean-Philippe Colombier +6 more
TL;DR: In this article, the phenomenon of light coupling to Marangoni convection flows is reported in an ultrashort laser-melted surface nanolayer destabilized by rarefaction wave resulting in the emergence of polarization-sensitive regular nanopatterns.
