Study of the Thermal and Hydrothermal Aging Effects on the Properties of 3D‐Printed Thermoplastic Polyurethane

Journal of Vinyl and Additive Technology, EarlyView.
Effect of post‐aging conditions on mechanical and thermal properties of FDM‐printed parts. ABSTRACT In this study, the thermal and hydrothermal aging of TPU produced with the FDM technique was simulated and subjected to a series of tests. The alterations in the internal structures of the samples that had been subjected to tensile, hardness, adhesive ...

‘The White Hordes From the West’: Race and Refuge in Australian Media Commentary About White Rhodesians During Zimbabwe's Decolonisation

Australian Journal of Politics &History, EarlyView.
ABSTRACT This article explores Australian media commentary on white Rhodesians migrating to Australia, focusing on the period of Malcolm Fraser's prime ministership (1975–1983). The main argument is that the Australian media debates about whether to classify white Rhodesians as ‘migrants’ or ‘refugees’ were not merely semantic but reflected a deeper ...

Investigation on high-temperature creep behavior at 300 °C in laser-welded joints of a novel heat-resistant Al alloy of Al–12Ce-0.4Sc

Journal of Materials Research and Technology
The scarcity of studies on the high-temperature creep behavior of laser welds in heat-resistant Al alloys limits their widespread application. This study examines the effects of laser welding and heat treatment on the high-temperature creep performance ...
