Finite Interface Dissipation Phase Field Modeling of Ni-Nb under Additive Manufacturing Conditions
Kubra Karayagiz, Luke Johnson, Raiyan Seede +8
During the laser powder bed fusion (L-PBF) process, the built part undergoes multiple rapid heating-cooling cycles, leading to complex microstructures with nonuniform properties. I…
Uncertainty Analysis of Microsegregation during Laser Powder Bed Fusion
Supriyo Ghosh, Mohamad Mahmoudi, Luke Johnson +3
Quality control in additive manufacturing can be achieved through variation control of the quantity of interest (QoI). We choose in this work the microstructural microsegregation t…
Single-Track Melt-Pool Measurements and Microstructures in Inconel 625
Supriyo Ghosh, Li Ma, Lyle E. Levine +4
We use single track laser melting experiments and simulations on Inconel 625 to estimate the dimensions and microstructures of the resulting melt pools. Our work is based on a desi…
