Design and Performance of Cold Bent Glass
… to ensure its safe performance after exposure to ageing. The recent availability of high strength glass provides an opportunity to address the first challenge by developing cold bent glass. Cold bending involves the straining of relatively thin glass components, at ambient temperatures, and is a …

Paint-bake effect on the plasticity and fracture of pre-strained aluminum 6451 sheets
… of 6000-series aluminum alloys through artificial ageing. Here, a comprehensive experimental program is carried out to characterize the anisotropic plasticity and the fracture initiation in prestrained artificially-aged aluminum 6451 sheets. It is found that the combination of …

Design and synthesis of new materials for the protection, restoration, and conservation of carbonate stone artifacts of interest in the field of Cultural Heritage.
… immersion, brushing, and spraying, followed by artificial ageing protocols to simulate realistic degradation. Treatments were evaluated through a comprehensive suite of analytical techniques, including SEM, optical microscopy, thin–section petrography, GID–XRD, and various physical and …

Germination responses of endemic land-races of Saudi-Arabian cereal species
… collected seeds and in material naturally or artificially aged under different storage conditions. Electrolyte leakage (measured as electrical conductivity) was evaluated as an indicator of deterioration of wheat seed quality. The germination responses to salinity of all five species showed …

Characterizing Organic Coatings on Renaissance Bronzes with Short-Wave Infrared and Mid-Infrared Spectroscopy
… the hard, insoluble coatings historically used. Artificial ageing was then applied to simulate long-term oxidation and polymerization. A spectral reference database was developed by analyzing coatings at each stage—raw, stoved, and aged—using ER-FTIR, FORS, and, selectively, pyrolysis gas …

Strength modelling of Al-Cu-Mg Type alloys
… a training root mean square error of 12MPa on an artificially aged 2024 alloy, the modelling accuracy on unseen yield strength data of two other alloys is 16MPa. Using a single set of parameters, the model has been applied to predict the hardness of a 2024-T351 alloy artificially aged at low …
