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 macroscopic yield stress. The evolution of the grains through 200 cycles reveals a continual change in von Mises stress and orientation across the entire specimen indicating a slow accumulation of plasticity even though the sample was cycled below its macroscopic yield. Grain reorientation is consistent with the development… 


Stress and deformation heterogeneity in individual grains within polycrystals subjected to fully reversed cyclic loading
Abstract The influence of spatial variability of the crystal stresses on the evolution of intragrain lattice misorientations during cyclic loading of a polycrystalline copper alloy is examined using
The development of grain-orientation-dependent residual stressess in a cyclically deformed alloy
A neutron diffraction investigation of the development of intergranular stresses, which vary as a function of grain orientations, in 316 stainless steel during high-cycle fatigue found that a large inter granular stress developed before cracks started to appear.
Intermittent plasticity in individual grains: A study using high energy x-ray diffraction
This work uses high energy x-ray diffraction measurements to build links from dislocation motion and structure development to stress relaxation by characterizing plastic deformation events inside individual deforming grains in both the titanium alloy, Ti-7Al, and the magnesium alloy, AZ31.
3-D growth of a short fatigue crack within a polycrystalline microstructure studied using combined diffraction and phase-contrast X-ray tomography
X-ray diffraction contrast tomography is a recently developed, non-destructive synchrotron imaging technique which characterizes microstructure and grain orientation in polycrystalline materials in
X-ray characterization of the micromechanical response ahead of a propagating small fatigue crack in a Ni-based superalloy
Abstract The small fatigue crack (SFC) growth regime in polycrystalline alloys is complex due to the heterogeneity in the local micromechanical fields, which result in high variability in crack
Study of grain-level deformation and residual stresses in Ti-7Al under combined bending and tension using high energy diffraction microscopy (HEDM)
Abstract In-situ high energy diffraction microscopy (HEDM) experiments are carried out to analyze the state of combined bending and tension in a Ti-7Al alloy under room temperature creep. Grain-level
In situ single-grain peak profile measurements on Ti–7Al during tensile deformation
Abstract High-energy three-dimensional X-ray diffraction with medium and high reciprocal space resolution was applied to study in situ tensile deformation of Ti–7Al specimens. Samples with planar and
