Homogenization Kinetics of a Nickel-based Superalloy Produced by Powder Bed Fusion Laser Sintering

January 26, 2017
Author(s)
Fan Zhang, Lyle E. Levine, Andrew J. Allen, Eric Lass, Sudha Cheruvathur, Mark R. Stoudt, Maureen E. Williams, Yaakov S. Idell, Carelyn E. Campbell
Additively manufactured (AM) metal components often exhibit fine dendritic microstructures and elemental segregation due to the initial rapid solidification and subsequent melting and cooling during the build process, which without homogenization would

Experimental characterization and crystal plasticity finite element modeling of heterogeneous deformation in commercial purity titanium

September 1, 2011
Author(s)
Y Yang, L. Wang, C. Zambaldi, P. Eisenlohr, R. Barabash, W. Liu, Mark R. Stoudt, M. A. Crimp, T. R. Bieler
Heterogeneous deformation, including local dislocation shear activity and lattice rotation, was analyzed in microstructure patches of polycrystalline, commercial purity titanium specimens using three different experimental methods. Crystal plasticity

Analysis of Deformation-Induced Surface Morphologies in Steel Sheet

July 1, 2005
Author(s)
Mark R. Stoudt, Joseph B. Hubbard
The surfaces of strained mild steel sheet specimens were examined with scanning laser confocal microscopy. Rigorous assessments were employed to establish the form of the roughness data. The small deviations from the ideal conditions observed in these
