Exploiting the rapid solidification potential of Laser Powder Bed Fusion in high strength and crack-free Al-Cu-Mg-Mn-Zr alloys KU Leuven
This work describes a systematic alloy design strategy resulting in the development of a high strength aluminum alloy adopted for L-PBF. First, based on the composition of a reference Al-Cu-Mg alloy, three Al-Cu-Mg-Mn-Zr-based alloys were investigated using computational thermodynamic tools. Subsequently, the L-PBF processing behavior, microstructure, and concomitant mechanical properties of the L-PBF-fabricated alloys were investigated. Alloys ...
Digital volume correlation for meso/micro in-situ damage analysis in carbon fiber reinforced composites KU Leuven
Recently, in-situ X-ray Computed Tomography (CT) has shown its potential for 3D damage analysis in composite materials. However, the characterization of damage in X-ray tomograms is not always straightforward, and it requires post-processing of the 3D images. In this study, we explore the potential of Digital Volume Correlation (DVC) for the detection and characterization of damage in fiber-reinforced composites, where fibers provide the ...
Bulk organic geochemical and palynofacies analyses of the Hettangian Datta Formation (Potwar Basin, Pakistan): Regional comparison with the time equivalent Lathi Formation (Jaisalmer Basin, India) KU Leuven
A detailed lithostratigraphic, bulk organic geochemical and palynofacies analyses were performed on organic-rich shale and coal samples from the Hettangian Datta Formation in the western Salt Range, southern Potwar Basin, Pakistan, to evaluate its hydrocarbon generation potential. Organic matter (OM) in the formation is mainly dominated by gas-prone Type III kerogen and oil- and gas-prone Type II kerogen. The coal and OM-rich shale intervals are ...
Arsenic anomalies in soils and rocks occurring in the southwestern part of the Grand Duchy of Luxembourg KU Leuven
Developing legislation on soil protection, including soil quality standards, is not straightforward for areas with high geogenic metal(loid) concentrations in rocks and soils. Several rock types in southern Luxembourg (laterally continuous into Northern France and Southern Belgium) contain elevated potentially toxic element concentrations. Toarcian and Aalenian Minette ironstones, and soils on top, possess high As concentrations (average of ~100 ...
