The globalization of the metals industry is resulting in extreme competitive pressures on the Canadian metals sector. As a result, there is increased awareness by Canadian companies such as Rio Tinto Alcan that they must focus on high valued added products. The current proposal is a collaboration between Rio Tinto Alcan and UBC to address this need. This project examines extrusion of 6xxx aluminum alloys which are used in a variety of applications including the construction and transportation sectors. The primary objective of this work is to develop knowledge based models for this process which will aid industry in improving the properties and quality of 6xxx products. The approach taken will be a combination of focused experiments and state of the art modelling techniques. The scope of the work will start with industrially produced as-cast alloys and then encompass the following aspects of the process: homogenization of the alloys, hot extrusion and artificial ageing. The benefits to Canada include i) the development and transfer of specific knowledge to the industrial partner, Rio Tinto Alcan, ii) the education of graduate students, and research associates (the need for highly qualified personnel has been identified by the industry) and iii) the expansion of internationally leading expertise on the physical metallurgy of aluminum alloys at UBC.

金属工业的全球化给加拿大金属部门带来了极大的竞争压力。因此，加拿大公司如力拓加铝公司越来越认识到，它们必须把重点放在高附加值产品上。目前的提案是力拓加铝和UBC之间的合作，以满足这一需求。该项目研究了用于各种应用的6xxx铝合金的挤压，包括建筑和运输部门。这项工作的主要目标是开发基于知识的模型，这将有助于行业提高6xxx产品的性能和质量。所采取的方法将是重点实验和最先进的建模技术相结合。工作范围将从工业生产的铸态合金开始，然后包括以下方面的过程：合金的均匀化，热挤压和人工时效。对加拿大的好处包括：i）开发和向工业合作伙伴Rio Tinto Alcan转让特定知识，ii）研究生和研究人员的教育（行业已确定需要高素质的人才）以及iii）在UBC扩展国际领先的铝合金物理冶金专业知识。
