In Situ Structural Characterization of Ageing Kinetics in Aluminum Alloy 2024 across Angstrom-to-Micrometer Length Scales

June 1, 2016
Author(s)
Fan Zhang, Lyle E. Levine, Andrew J. Allen, Carelyn E. Campbell, Adam Abel Creuziger, Nataliya Kazantseva, Jan Ilavsky
The precipitate structure and precipitation kinetics in an Al-Cu-Mg alloy (AA2024) aged at 190 °C, 208 °C, and 226 °C have been studied using ex situ TEM and in situ synchrotron-based, combined ultra-small angle X-ray scattering, small angle X-ray

Structural study of epitaxial LiCoO2 films grown by PLD on single crystal SrTiO3 substrates

May 24, 2016
Author(s)
Leonid A. Bendersky, Zhipeng Li, S. Yasui, Saya Takeuchi, Adam A. Creuziger, S. Maruyama, Andrew A. Herzing, I Takeuchi
Epitaxial LiCoO2 (LCO) thin films of different orientations were
 fabricated by pulsed laser deposition (PLD) in order to model single-crystal
 behavior of intercalation cathodes during electrochemical reactions. This paper demonstrates that
(1) epitaxial

Thermally-activated constitutive model including dislocation interactions, aging and recovery for strain path dependence of solid solution strengthened alloys: Application to AA5754-O

December 1, 2015
Author(s)
Minh-Son Pham, Mark A. Iadicola, Adam A. Creuziger, Lin Hu, Anthony D. Rollett
A thermally-activated constitutive model is developed based on dislocation interactions, crystallographic orientations and microstructural evolution to describe the elasto-plastic stress-strain behavior during multi-axial loading. The aim is to contribute

Constitutive Modeling based on Evolutionary Multi-junctions of Dislocations

May 7, 2014
Author(s)
Minh-Son Pham, Adam A. Creuziger, Mark A. Iadicola, Timothy J. Foecke, A.D. Rollett
A latent hardening model based on the binary junction-induced hardening can effectively describe the plastic anisotropic response. However, this approach still has some descriptive and predictive limitations. Recent findings show that binary junctions

Advanced Biaxial Cruciform Testing at the NIST Center for Automotive Lightweighting

January 1, 2014
Author(s)
Mark A. Iadicola, Adam A. Creuziger, Timothy J. Foecke
Modeling of sheet metal forming operations requires mechanical properties data at very large tensile strains and various biaxial strain paths. Typically these data are developed along strain ratio paths that are linear and monotonic, but actual forming

Ti_(12.5)Zr_(21)V_(10)Cr_(8.5)Mn_(x)Co_(1.5)Ni_(46.5-x)AB_(2)-type metal hydride alloys for electrochemical storage application: Part 1. Structural characteristics

August 3, 2012
Author(s)
Leonid A. Bendersky, Ke Wang, Igor Levin, Dale E. Newbury, K. Young, B. Chao, Adam A. Creuziger
The microstructures of a series of AB_(2)-based metal hydride alloys (Ti_(12.5)Zr_(21)V_(10)Cr_(8.5)Mn_(x)Co_(1.5)Ni_(46.5-x)) designed to have different fractions of non-Laves secondary phases were studied by x-ray diffraction, scanning electron

A Model for Calculating Diffraction Elastic Constants

January 18, 2012
Author(s)
Thomas H. Gnaeupel-Herold, Adam A. Creuziger, Mark A. Iadicola
An alternate model is proposed to calculate the diffraction elastic constants from the elastic constants of the single crystal. It is based on the inverse elastic susceptibility and thus it is related to the elastic polarization approach widely known as
