Journal ArticleDOI
Controlling mechanical properties of additively manufactured hastelloy X by altering solidification pattern during laser powder-bed fusion
Ali Keshavarzkermani,Reza Esmaeilizadeh,Usman Ali,Pablo D. Enrique,Yahya Mahmoodkhani,Norman Y. Zhou,Ali Bonakdar,Ehsan Toyserkani +7 more
TL;DR: In this article, the effect of scanning strategies and build orientations on solidification patterns in the printed LPBF Hastelloy X parts was studied. And the as-built microstructure (grain size, texture) and mechanical responses (yield strength, ultimate tensile strength (UTS), and elongation) were also presented.
Journal ArticleDOI
An investigation into the effect of process parameters on melt pool geometry, cell spacing, and grain refinement during laser powder bed fusion
Ali Keshavarzkermani,Ehsan Marzbanrad,Reza Esmaeilizadeh,Yahya Mahmoodkhani,Usman Ali,Pablo D. Enrique,Norman Y. Zhou,Ali Bonakdar,Ehsan Toyserkani +8 more
TL;DR: In this paper, the effect of laser energy density on the melt pool geometry and microstructure of Hastelloy X single tracks produced by fixed LED values at different laser powers and scanning velocities was investigated.
Journal ArticleDOI
Customizing mechanical properties of additively manufactured Hastelloy X parts by adjusting laser scanning speed
Reza Esmaeilizadeh,Ali Keshavarzkermani,Usman Ali,Yahya Mahmoodkhani,B. Behravesh,Hamid Jahed,Ali Bonakdar,Ehsan Toyserkani +7 more
TL;DR: In this article, the effect of laser scanning speed, one of the main process parameters in laser powder-bed fusion (LPBF), on the quasi-static tensile response of Hastelloy X at room temperature was investigated.
Journal ArticleDOI
Topology optimization parallel-computing framework based on the inherent strain method for support structure design in laser powder-bed fusion additive manufacturing
Zhidong Zhang,Osezua Ibhadode,Usman Ali,Chinedu Francis Dibia,Pouyan Rahnama,Ali Bonakdar,Ehsan Toyserkani +6 more
TL;DR: The proposed framework is used to design stiffer support structures to reduce the before and after-cutting deflections in printed cantilevers to achieve over 60% reduction in part deflection and over 50% material usage reduction.
Journal ArticleDOI
Finite element modeling of the electron beam welding of Inconel-713LC gas turbine blades
TL;DR: In this paper, a comprehensive numerical analysis has been carried out using ABAQUS software to predict the level of thermal and residual stresses as well as distortions in FZ and HAZ of the electron beam welded shrouds.
