“…It provides high resolution images (on the order of 10 nm) along with a large enough volume to provide statistically accurate information of nano-scale precipitates. FIB tomography has already been successfully utilized to characterize the microstructure in Al-SiC nanolaminates [33], Pb-free solders [34,35], and superalloys [36,37].…”

The size and distribution of precipitates in Al 7075 alloys affects both the mechanical and corrosion behavior (including stress corrosion cracking and fatigue corrosion) of the alloy. Three dimensional (3D) quantitative microstructural analysis of Al 7075 in the peak aged condition (T651) allows for a better understanding of these behaviors. In this study, Focused ion beam (FIB) tomography was used to characterize the microstructure in three dimensions. Analysis of grains and precipitates was performed in terms of volume, size, and morphology. It was found that the precipitates at the grain boundaries are larger in size, higher in aspect ratios and maximum Feret diameter compared to the precipitates inside the grains, due to earlier nucleation of the precipitates at the grain boundaries. Our data on the precipitates at the interface between grains and Mg 2 Si inclusion show that the surfaces of inclusion (impurity) particles can serve as a location for heterogeneous nucleation of precipitates.

“…Both SRCT and SRCL are used with a large variety of contrast modes such as phase contrast (Cloetens et al, 1999;Weitkamp et al, 2005;Harasse et al, 2011;Altapova et al, 2012), fluorescence (de Jonge & Vogt, 2010;Xu et al, 2012a) and diffraction contrast (Ludwig et al, 2008;Hä nschke et al, 2012) which have many applications in materials research (Yazzie et al, 2012;Boden et al, 2014), microsystem technology, cultural heritage, paleontology (Riedel et al, 2012) and biology (Walker et al, 2014; de Kamp et al, 2015;Greven et al, 2015).…”

Real-time image-content-based beamline control for smart 4D X-ray imaging

et al. 2016

Real-time processing of X-ray image data acquired at synchrotron radiation facilities allows for smart high-speed experiments. This includes workflows covering parameterized and image-based feedback-driven control up to the final storage of raw and processed data. Nevertheless, there is presently no system that supports an efficient construction of such experiment workflows in a scalable way. Thus, here an architecture based on a high-level control system that manages low-level data acquisition, data processing and device changes is described. This system is suitable for routine as well as prototypical experiments, and provides specialized building blocks to conduct four-dimensional in situ, in vivo and operando tomography and laminography.

“…They simulated the mechanical and thermal properties of these composites by finite element modeling and successfully compared their model results to conventional compression and thermal expansion tests. In another study of non-destructive test methods, Yazzie et al (2012) used 3D X-ray synchrotron tomography and focused ion beam tomography to visualize and quantify Sn-3.5Ag, Sn-0.7Cu, and Sn-37Pb solder joints. Xu et al (2014) used a reconstruction algorithm methodology to construct 3D microstructures of samples based on 2D images at the microscale.…”

The Diametrically Loaded Cylinder for the Study of Nanostructured Aluminum–Graphene and Aluminum–Alumina Nanocomposites Using Digital Image Correlation

Non-contact methods for characterization of metal matrix composites have the potential to accelerate the development and study of advanced composite materials. In this study, diametrical compression of small disk specimens was used to understand the mechanical properties of metal matrix micro-and nanocomposites. Analysis was performed using an inverse method that couples digital image correlation and the analytical closed-form formulation. This technique was capable of extracting the tension and compression modulus values in the metal matrix nanocomposite (MMNC) disk specimens. Specimens of aluminum and aluminum reinforced with either Al 2 O 3 nanoparticles or graphene nanoplatelets were synthesized using a powder metallurgy approach that involved room temperature milling in ethanol and low temperature drying followed by single action compaction. The elastic and failure properties of MMNC materials prepared using the procedure above are presented.
