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 Ford and 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 Ford, Rio Tinto Alcan, University of Waterloo and UBC to address this need. This project examines 6xxx aluminum extrusion alloys which are used for a variety of parts in automobiles and light trucks. The primary objective of this work is to develop knowledge based models 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: 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 partners, Ford and Rio Tinto Aluminium, 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，人们越来越认识到，加拿大的公司，如福特和力拓铝业，他们必须把重点放在高附加值的产品，减少车辆的重量。目前的提议是福特、力拓加铝、滑铁卢大学和不列颠哥伦比亚大学之间的合作，以满足这一需求。本项目研究用于汽车和轻型卡车各种零件的6xxx铝挤压合金。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，然后涵盖该工艺的以下方面：挤压、淬火和随后用于提高强度的热处理。对加拿大的好处包括：i）向工业合作伙伴福特和力拓铝业发展和转让具体知识，ii）研究生和博士后研究员的教育（行业已经确定了对高素质人才的需求）和iii）在UBC和Waterloo扩展国际领先的铝合金物理冶金专业知识。
