Through process modelling of next generation heavy gauge line pipe

该提案汇集了来自不列颠哥伦比亚省大学、麦克马斯特大学、Evraz NA Inc.与TC Energy合作，以应对生产先进厚钢板的挑战，这些钢板具有建造和更换现有和未来管道所需的性能。这一挑战对于在竞争性经济框架内确保最高水平的安全性和可持续性至关重要。研究中采用的方法涉及所谓的“全过程”方法，其中可以说明制造过程中不同步骤（此处为热轧）之间的明确联系。对于厚（也称为“大规格”）管材料的特别挑战是由于这些产品的加工中固有的温度和变形梯度而产生的特性的贯穿厚度变化。该提案将利用最先进的建模方法和新的先进表征技术。这项工作的结果将是i）在科学文献中发表的控制先进管线钢强度和韧性的基本机制的新知识，ii）3名博士生的教育，2名博士后研究员和1名研究工程师，研究领域对加拿大至关重要，以及iii）将知识转移给将在加拿大和全球市场上将成果商业化的行业合作伙伴。

This proposal brings together an established team of researchers from The University of British Columbia, McMaster University, Evraz NA Inc. and TC Energy to tackle the challenge of producing advanced thick steel plate with the required properties for the construction and replacement of existing and future pipelines. This challenge is critical to ensure the highest level of safety and sustainability within a competitive economic framework. The approach taken in the research involves a so called "through process" methodology where explicit links between the different steps in the manufacturing process, here hot rolling, can be accounted for. A particular challenge for thick (also known as "heavy gauge") pipe materials are the through thickness variation of properties that develop due to the temperature and deformation gradients inherent in the processing of these products. The proposal will take advantage of state of the art modelling approaches and new advanced characterization techniques. The result of this work will be i) new knowledge on the fundamental mechanisms which control strength and toughness of advanced pipeline steels to be published in the scientific literature, ii) the education of 3 PhD students, 2 postdoctoral fellows and 1 research engineer in a field of critical importance to Canada and iii) the transfer of knowledge to the industry partners who will commercialize results in the Canadian and global market.
