Thermodynamic Modeling of Pure Elements from 0 K with Uncertainty Quantification using PyCalphad and ESPEI
Alexander Richter, Abdulmonem Obaied, Irina Roslyakova +3
Thermodynamic modeling of pure elements is the foundation of the CALPHAD modeling of engineering materials. Recently, multiple physics-based models have been proposed to describe G…
Thermodynamic modeling of binaries in Cr-Fe-Mo-Nb-Ni supported by first-principles calculations
Hui Sun, Shun-Li Shang, Shuang Lin +3
Thermodynamic descriptions of all binaries within the Cr-Fe-Mo-Nb-Ni system have been complied and, where necessary, remodeled. Notably, the Cr-Fe and Fe-Mo systems have been remod…
Effect of Anisotropic Peierls Barrier on the Evolution of Discrete Dislocation Networks in Ni
John D. Shimanek, Darshan Bamney, Laurent Capolungo +2
Over low and intermediate strain rates, plasticity in face centered cubic (FCC) metals is governed by the glide of dislocations, which manifest as complex networks that evolve with…
Tensile behavior of stainless steel 304L to Ni-20Cr functionally graded material: experimental characterization and computational simulations
Lourdes D. Bobbio, Brandon Bocklund, Zi-Kui Liu +1
This study presents experimental and computational analyses of the phase composition and mechanical behavior of a functionally graded material (FGM) grading from 100 vol% 304L stai…
Scheil-Gulliver simulations for the design of functionally graded alloys by additive manufacturing using pycalphad
Brandon Bocklund, Lourdes D. Bobbio, Richard A. Otis +2
Additive manufacturing (AM), through directed energy deposition, supports planned composition changes between locations within a single component, allowing for functionally graded…
