Analysis of a Three-Dimensional Slip Field in a Hexagonal Ti Alloy from in-situ High-Energy X-ray Diffraction Microscopy Data
Darren C. Pagan, Kelly E. Nygren, Matthew P. Miller
Here we analyze a three-dimensional distribution of crystallographic slip measured in-situ during the uniaxial deformation of hexagonal Ti-7Al. The slip field is reconstructed usin…
Three-Dimensional In Situ Texture Development and Plasticity Accumulation in the Cyclic Loading of an alpha-Ti Alloy
Rachel E. Lim, Joel V. Bernier, Darren C. Pagan +2
High-energy synchrotron x-rays are used to track grain rotations and the micromechanical evolution of a hexagonal Ti-7Al microstructure as it is cyclically loaded below its macrosc…
Grain-Resolved Temperature-Dependent Anisotropy in Hexagonal Ti-7Al Revealed by Synchrotron X-Ray Diffraction
Rachel E. Lim, Darren C. Pagan, Donald E. Boyce +3
Hexagonal metals have anisotropic coefficients of thermal expansion causing grain-level internal stresses during heating. High energy x-ray diffraction microscopy, a non-destructiv…
Three-dimensional in situ characterization of phase transformation induced austenite grain refinement in nickel-titanium
Ashley N. Bucsek, Lee Casalena, Darren C. Pagan +4
Near-field and far-field high-energy diffraction microscopy and microcomputed tomography X-ray techniques were used to study a bulk single crystal nickel-titanium shape memory allo…
Ferroelastic twin reorientation mechanisms in shape memory alloys elucidated with 3D X-ray microscopy
Ashley N. Bucsek, Darren C. Pagan, L. Casalena +3
Three-dimensional (3D) X-ray diffraction methods were used to analyze the evolution of the load-induced rearrangements of monoclinic twin microstructures within bulk nickel-titaniu…
Probing local lattice distortion in medium- and high-entropy alloys
Y. Tong, G. Velisa, T. Yang +9
The atomic-level tunability that results from alloying multiple transition metals with d electrons in concentrated solid solution alloys (CSAs), including high-entropy alloys (HEAs…
