Summary: This paper describes a new residual strain mapping program at the Advanced Photon Source, Argonne National Laboratory. Based on energy dispersive x-ray diffraction, the program is capable of accurately measuring the residual strain field of engineering alloys with high spatial and strain resolution, while providing a complementary view of the structure for a better understanding of the measured strain field.

Summary: In this study, the changes in unit cell volume, Bragg peak full width at half maximum (FWHM), and integrated intensity were monitored in 8 % Y2O3 stabilized ZrO2 (8 %YSZ) solid state electrolyte during a triple-flash sintering experiment. The results showed spontaneous singularities at different temperatures under applied field intensity, which were associated with current draw and density increase. The observations contribute to understanding the flash sintering process.

Summary: The Bravais lattice parameters of a strained Ge quantum well grown on a SiGe/Si virtual substrate hosting two hole spin qubits are determined using synchrotron-based scanning X-ray diffraction microscopy. The three-dimensional spatial dependence of the six strain tensor components is rendered with a lateral resolution of approximately 50 nm. Different spatial scales governing the strain field fluctuations in proximity of the qubits are observed, with short-ranged fluctuations linked to compressive stressing action and longer-ranged fluctuations associated with misfit dislocations in the virtual substrate.

Summary: This study used energy dispersive diffraction (EDD) with polychromatic synchrotron x-radiation to investigate the spatial organization of mineral phase and crystallographic texture in shark vertebrae. The results show differences in c-axis orientation of bioapatite in shark centra from different orders, indicating functional differences. The study suggests that the 3D EDD-derived maps can inform future numerical models of shark centra under applied load.

Summary: This study investigates the effect of Strain Path Changes (SPCs) on the mechanical properties and crystal-level features of deformation in a single phase, ferritic steel. The results show that abrupt strain paths significantly reduce ductility, and the pre-strain direction has a major influence on the macroscopic response and texture configuration. Increasing pre-strain magnitudes result in a stagnation of lattice strain hardening rates and a significant increase in Geometrically Necessary Dislocation (GND) densities. There is no correlation found between GND density and grain orientation, indicating that the initial texture and texture developed in pre-strain play a decisive role in determining ductility.

Summary: Accurate residual lattice strain measurements rely on precise diffraction peak locations and suitable microstructures. Analyzing sampling statistics and roughness helps reduce strain measurement uncertainty. The microstructural suitability dominates measurement uncertainty when the number of illuminated grains is less than 10^6, as observed in monochromatic and energy dispersive X-ray diffraction experiments.

Summary: The effect of boron doping on the stacking fault energy of Fe50_XMn30Co10Cr10BX multi-component alloys was experimentally and computationally assessed. It was found that increasing boron content resulted in higher stacking fault energy, leading to changes in deformation mechanisms and martensitic transformation.

Summary: In this study, the orientation evolution of cold-rolled Cu foils during heating was investigated, and the results showed a transition from the cold-rolling texture to a recrystallization texture dominated by two rotated orientations. The formation of the recrystallization texture was influenced by both intrinsic microstructural factors and extrinsic geometrical factors. The post-nucleation growth was affected by the biaxial thermal elastic constraint and surface energy, resulting in a mixed texture at the completion of recrystallization. The coherent Sigma 3 boundaries stabilized the growth of the new components.

Summary: The shipbuilding industry is focusing on developing digital twin technology, but the lack of material processing data in simulations affects the accuracy of structural performance. Integrated Computational Materials Engineering (ICME) techniques link digital information across multiple length scales to reduce the time and cost of physical testing needed for validation. This study validates the materials-informed digital twin method through physical specimen selection, finite-element analysis (FEA) based welding simulations, and comparison of predicted strain data with experimental results using energy dispersive diffraction (EDD) techniques.

Summary: This study investigates the mechanisms of strain and texture observed in MAPbI(3) thin films deposited on various oxide substrates. The results show that the strain of the perovskite layers is essentially relaxed behavior, contradicting the commonly accepted hypothesis. The texture in the perovskite layers is studied using synchrotron full-field diffraction X-ray microscopy, and the stability of different orientations is analyzed by DFT calculations.

Summary: Assessing local residual stress and orientation within steel grains at nanometer resolution remains challenging. Using dark field X-ray microscopy, 3D lattice variations in pearlitic steel were mapped, showing orientation variations and compressive elastic strain. These variations impact manufacturing processes and mechanical properties, but there is no direct correlation between measured compressive strain and lattice orientation.

Summary: An effective route of customizing the superelasticity (SE) of NiTi shape memory alloys via modifying the grain structure was explored. It was found that the smaller the grain size, the higher the phase transformation nucleation kinetics, and the lower the propagation kinetics. Stress concentration happens near high-angle grain boundaries, while no obvious stress concentration can be observed in low-angle grain boundary structures. The statistical distribution of strain becomes asymmetric during loading.

Summary: Mechanical surface modification techniques, such as shot peening, can improve the fatigue properties of metals and other materials. Cavitation peening is a special variation of shot peening that offers the advantage of lower surface roughness and no solid collisions. Understanding both fluid dynamics and materials science is necessary for grasping the mechanisms of cavitation peening. This comparative review presents key insights and achievements, comparing water jet, pulsed laser, and ultrasonic cavitation peening with traditional shot peening.
