A method for pole figure measurements via a dynamic segmented spiral scheme

February 1, 2023
Author(s)
Surya Chandramouleeswaran, Adam Creuziger, Kip Findley
A new method for pole figure measurement is described, titled a dynamic segmented spiral scheme. Compared to schemes currently in use, the dynamically segmented spiral scheme was shown to have advantages in term of evenness of pole figure coverage, time

June 12, 2021
Author(s)
Alec Saville, Sven Vogel, Adam Abel Creuziger, Jake Benzing, Adam Pilchak, Lee Semiatin, Peeyush Nandwana, Kester Clarke, Jonah Klemm-Toole, Amy Clarke
Metal additive manufacturing (AM) enables customizable, on-demand parts, allowing for new designs and improved engineering performance. Unfortunately, the ability to control AM metal alloy microstructures is still lacking, especially when considering

Location-specific Microstructure Characterization Within IN625 Additive Manufacturing Benchmark Test Artifacts

March 3, 2020
Author(s)
Mark R. Stoudt, Maureen E. Williams, Lyle E. Levine, Adam Abel Creuziger, Sandra A. Young, Jarred C. Heigel, Brandon Lane, Thien Q. Phan
Additive manufacturing (AM) of metals creates segregated microstructures with significant differences from those of traditional wrought alloys. Understanding how the local build conditions generate specific microstructures is essential for developing post

Insights into Cruciform Sample Design

January 30, 2017
Author(s)
Adam A. Creuziger, Mark A. Iadicola, Timothy J. Foecke, Evan Rust, Dilip K. Banerjee
Four different cruciform sample designs, based on the work of Abu-Farha et al, were studied in this paper. The original design of Abu-Farha was validated at room temperature for a thicker sample, and two modified sample geometries that would permit thinner

Crystal Plasticity Analysis of Constitutive Behavior of 5754 Aluminum Sheet

June 30, 2016
Author(s)
Minh-Son Pham, Anthony D. Rollett, Adam Abel Creuziger, Mark Iadicola, Timothy J. Foecke
Crystal plasticity constitutive equations for the multi-axial stress-strain behavior of aluminum alloy 5754 sheets have been developed. A Taylor model, a self-consistent visco-plastic model and an N-site model based on the Fast Fourier Transform were used

FEA parameter verification for strain localization experiments

June 6, 2016
Author(s)
Mark A. Iadicola, Dilip K. Banerjee, Adam A. Creuziger
Multi-axial specimen geometry optimization through finite element analysis requires robust models that incorporate the critical physics of the experiment as well as a sufficiently robust constitutive law. This can be difficult even at low nominal strain
