In-situ observations of cyclic deformation in an extruded Mg-2Nd-1Y-0.1Zr-0.1Ca alloy

Arianna Mena, Jiashi Miao, Daniel P. Veghte, Bruce W. Williams et autres

In this study, the evolution of deformation mechanisms during cyclic loading in an extruded, solution-treated Mg–2Nd–1Y–0.1Zr–0.1Ca alloy was investigated using a combination of in-situ loading, scanning electron microscopy (SEM), electron backscatter diffraction (EBSD), and focused ion beam (FIB) nanofabrication. The initial microstructure …

Fluid-Structure Interaction Modelling to Predict Rupture of Dense-Phase CO2 Pipeline

Bruce W. Williams, Ifaz T. Haider, Dean Difiore, C. Hari Manoj Simha et autres

Abstract Fracture resistance in a rupturing pipeline is influenced by the pressure exerted on the flaps of the pipeline by the decompressing fluid. Current engineering methodologies mainly treat the fracture resistance curve and the decompression curve as uncoupled. To capture the coupled …

Development and characterisation of improved unifocal primary mouse lung cancer models with metastatic potential

Ana‐Rita Pedrosa, Alejandro Castillo‐Kauil, Y. S. Kravchuk, Louise E. Reynolds et autres

Abstract Lung cancer is the leading cause of cancer‐related death globally. To better understand the biology of lung cancer, mouse models have been developed using either tail vein‐injected tumour cell lines or genetically modified mice. The current gold‐standard models typically present with …

Engineering Approach for Ductile Fracture Arrest Based on CTOA

Su Xu, Chris Bassindale, Xin Wang, Bruce W. Williams et autres

Abstract Ductile fracture propagation control and arrest are important elements in fracture control of pipelines transporting natural gas and other high-vapour-pressure media (e.g., dense-phase carbon dioxide). The most familiar crack arrest methodology, the Battelle Two-Curve Method (BTCM), is based on Charpy absorbed …

Joining of Zirconium Alloys to Nickel Bearing Alloys for In-Core Components

M. Gaudet, Anne McLellan, A.P. Gerlich, Bruce W. Williams

Abstract Zirconium alloys are well-positioned as the material of choice for nuclear in-core structures since they have a low neutron absorption cross section and possess good material properties under elevated neutron flux and high-temperature operating conditions. The Canadian supercritical water-cooled reactor (SCWR) …

Damage Model Prediction of Crack Initiation and Propagation in Five Fracture Geometries for X80 Pipeline Steel

Bruce W. Williams, Jia Xue, Su Xu, Dong-Yeob Park et autres

Abstract Test specimens used to calibrate damage-mechanics models are designed to produce a range of stress triaxialities and Lode angles to accurately capture the fracture envelope of the metal. Many of these specimens have lower constraint than deeply notched fracture specimens that …

A Method for Comparing the Fatigue Performance of Forged AZ80 Magnesium

Andrew Gryguć, Seyed Behzad Behravesh, Hamid Jahed, Mary A. Wells et autres

A closed die forging process was developed to successfully forge an automotive suspension component from AZ80 Mg at a variety of different forging temperatures (300 °C, 450 °C). The properties of the forged component were compared and contrasted with other research works …
