In the present work, a novel Laser Directed Energy Deposition (LDED) process planning methodology is proposed to build a dome structure with variable overhang angles. Overhang structures with different overhang angles were built where the maximum angle of 35° can be used to build overhang...

In this study, a new grade of Inconel 718 alloy (IN718) strengthened by nano-oxides have been designed and produced. The alloy composition of 0.3 wt.% Y 2 O 3 – IN718 has been determined using CALPHAD based thermochemical modelling approach. Designed ODS-IN718 alloy is produced by Selective...

In this research, a room temperature multicycle nanoindentation technique was implemented to evaluate the effects of the laser peening (LP) process on the surface mechanical behavior of additively manufactured (AM) Inconel 625. Repetitive deformation was introduced by loading-unloading during an...
