Uncertainty Propagation in a Multiscale CALPHAD-Reinforced Elastochemical Phase-field Model
Vahid Attari, Pejman Honarmandi, Thien Duong +3
ICME approaches provide decision support for materials design by establishing quantitative process-structure-property relations. Confidence in the decision support, however, must b…
The Effect of Chemical Disorder on Defect Formation and Migration in Disordered MAX Phases
Prashant Singh, Daniel Sauceda, Raymundo Arroyave
MAX phases have attracted increased attention due to their unique combination of ceramic and metallic properties. Point-defects are known to play a vital role in the structural, el…
Probing discontinuous precipitation in U-Nb
Thien Duong, Robert E. Hackenberg, Vahid Attari +3
U-Nb's discontinuous precipitation, , is intriguing in the sense that it allows formation and growth of the…
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…
Electromigration Response of Microjoints in 3DIC Packaging Systems
Vahid Attari, Thien Duong, Raymundo Arroyave
In multilevel 3D integrated packaging, three major microstructures are viable due to the application of low volume of solders in different sizes, and/or processing conditions. Ther…
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…
Fast Exact Computation of Expected HyperVolume Improvement
Guang Zhao, Raymundo Arroyave, Xiaoning Qian
In multi-objective Bayesian optimization and surrogate-based evolutionary algorithms, Expected HyperVolume Improvement (EHVI) is widely used as the acquisition function to guide th…
