The globalization of the automotive sector is resulting in extreme competitive pressures on the Canadian metals sector. As a result, there is increased awareness that Canadian based companies such as Rio Tinto Aluminium that they must focus on high value added products which reduce the weight of vehicles. The current proposal is a collaboration between Rio Tinto Aluminium, the University of Waterloo and the University of British Columbia to address the need for higher performance aluminum alloys. This project examines high strength 6xxx aluminum extrusion alloys containing copper which can be used for a variety of parts in automobiles and light trucks. The primary objective of this work is to develop knowledge based models which span the entire process from casting to the final heat treatment. This will aid the industry to improve 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 extrusion, quenching and the subsequent heat treatment which is used to increase strength. The benefits to Canada include i) the development and transfer of specific knowledge to the industrial partner, Rio Tinto Aluminum, ii) the education of graduate students and postdoctoral fellows (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 and Waterloo.

汽车行业的全球化给加拿大金属行业带来了极大的竞争压力。因此，人们越来越意识到，加拿大公司，如力拓铝业，他们必须专注于高附加值的产品，减少车辆的重量。目前的提案是力拓铝业、滑铁卢大学和不列颠哥伦比亚省大学之间的合作，以满足对更高性能铝合金的需求。本项目研究高强度含铜6xxx铝挤压合金，可用于汽车和轻型卡车的各种零件。这项工作的主要目标是开发基于知识的模型，它跨越了从铸造到最终热处理的整个过程。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，然后包括以下工艺方面：均质化挤压、淬火和用于提高强度的后续热处理。对加拿大的好处包括：i）向工业合作伙伴Rio Tinto Aluminum开发和转让特定知识，ii）研究生和博士后研究员的教育（行业已确定对高素质人才的需求）以及iii）在UBC和Waterloo扩展国际领先的铝合金物理冶金专业知识。
