Understanding the near-threshold crack growth behavior in an aluminum alloy by x-ray tomography

Understanding the near-threshold crack growth behavior in an aluminum alloy by x-ray tomography

The near-threshold behavior of long cracks is evaluated using pre-cracked flat dogbone specimens of a commercial aluminum alloy in two heat treatment states. Once the threshold was known, the crack initially introduced by cyclic compression was propagated under load control with approximately
constant range of the stress intensity factor at values close to the threshold values. The 3D morphology of the crack and the spatial distribution of the primary precipitates obtained by µ-CT were... Read more

3D characterization of the fracture mechanisms of a Fe-rich Al-Si-Cu alloy

3D characterization of the fracture mechanisms of a Fe-rich Al-Si-Cu alloy

The effect of the defect size and morphology on the fatigue damage evolution was analysed in a recycled Al-Si-Cu alloy by micro-computed tomography and scanning electron microscopy. Fatigue tests were performed and the different crack initiation scenarios were characterized and classified. The interaction between shrinkage and gas pores was the key crack initiation mechanism and the ß-Al5FeSi particles did not play any role in the crack initiation phase. However, crack path analysis indicate... Read more

REGIONAL DIVERSITY IN THE MURINE CORTICAL VASCULAR NETWORK IS REVEALED BY SYNCHROTRON X-RAY TOMOGRAPHY AND IS AMPLIFIED WITH AGE

REGIONAL DIVERSITY IN THE MURINE CORTICAL VASCULAR NETWORK IS REVEALED BY SYNCHROTRON X-RAY TOMOGRAPHY AND IS AMPLIFIED WITH AGE

Cortical bone is permeated by a system of pores, occupied by the blood supply and osteocytes. With ageing, bone mass reduction and disruption of the microstructure are associated with reduced vascular supply. Insight into the regulation of the blood supply to the bone could enhance the understanding of bone strength determinants and fracture healing. Using synchrotron radiation-based computed tomography, the distribution of vascular canals and osteocyte lacunae was assessed in murine cortica... Read more

Evolution of damage during the fatigue of 3D woven glass-fibre reinforced composites subjected to tension–tension loading observed by time-lapse X-ray tomography

Evolution of damage during the fatigue of 3D woven glass-fibre reinforced composites subjected to tension–tension loading observed by time-lapse X-ray tomography

Three dimensional (3D) composites were proposed over 40 years ago in an attempt to overcome the shortcomings of 2D laminates, by incorporating fibres into the through-thickness direction. 3D weaving offer significant manufacturing benefits as well as creating versatile textiles having a range of 3D architectures.

The development of fatigue damage in a glass fibre modified layer-to-layer three dimensional (3D) woven composite has been followed by time-lapse X-ray computed tomograp... Read more

A statistical assessment of ductile damage in 304L stainless steel resolved using X-ray computed tomography

A statistical assessment of ductile damage in 304L stainless steel resolved using X-ray computed tomography

X-ray computed tomography (XCT) has been shown to reveal the true extent of ductile damage below the fracture surface of failed test specimens, which is often significantly underestimated when probed using 2D serial sectioning techniques and a microscope, since a single plane of material may only exhibit only a handful of resolvable voids.

In contrast XCT offers the capability to generate large datasets consisting of hundreds, if not thousands, of individually resolvable voids, where e... Read more

The microstructure of food affects our sensorial perception, its attractiveness, and the manufactured product’s shelf-life.

Microstructural evolution in soft matter directly influences not only the material’s mechanical and functional properties, but also our perception of that material’s taste. Using synchrotron X-ray tomography and cryo-SEM we investigated the time–temperature evolution of ice cream’s microstructure. This was enabled via three adv... Read more

A Structure and Durability Comparison of Membrane Electrode Assembly Fabrication Methods: Self-Assembled Versus Hot-Pressed

A Structure and Durability Comparison of Membrane Electrode Assembly Fabrication Methods: Self-Assembled Versus Hot-Pressed

The most common means of fabricating membrane electrode assemblies (MEAs) for polymer electrolyte fuel cells (PEFCs) involves a hot-press step. The conditions used to perform the hot-press impacts the performance and durability of the fuel cell.

However, the hot-press process is not essential for achieving operational MEAs and some practitioners dispense with the hot-press stage altogether by using a self-assembled approach. By performing the integration of the components in-situ durin... Read more
