One of the most significant global challenges Canada faces in the 21st century is continuing to maintain a strong economic position in the highly competitive primary metals extraction and processing sector. In order for Canada to continue to play a global leadership role in this sector, it is imperative that novel and state of the art manufacturing techniques for advanced metallic systems are exploited. The proposed research program will continue to build on the applicant's area of research expertise in experimental measurements and the development of knowledge-based process models for advanced metallic products and manufacturing processes. This program will focus on novel clad metallic systems produced via co-casting. For the first time, clad metallic sheet produced via co-casting, creates the possibility of tailoring the surface properties of the sheet relative to its centre in a cost effective way. Current examples of clad aluminum sheet used commercially include: brazing sheet for heat exchangers and Al-clad series of aerospace alloys. Presently, these clad sheets are produced via a costly roll bonding technology whereby the two sheets are rolled together under high pressure to create the clad sheet. This research program will create and develop a range of clad aluminum sheet products and measure how these clad products respond to industrially relevant thermo-mechanical treatments such as homogenization, hot/cold rolling and final heat treatment. In particular emphasis will be placed on understanding the metallurgical reactions that occur close to the interface in these systems and the interaction of solute across the interface during manufacturing operations.

加拿大21世纪最重大的全球挑战之一是继续在高度竞争性的原产金属提取和加工部门中保持强大的经济地位。为了使加拿大继续在该领域扮演全球领导角色，必须利用高级金属系统的新颖和状态制造技术。 拟议的研究计划将继续基于申请人在实验测量方面的研究专业知识以及为高级金属产品和制造过程开发基于知识的过程模型的领域。该程序将重点关注通过共铸造产生的新型包装金属系统。首次通过共铸造产生的覆层金属板创造了以具有成本效益的方式调整纸张相对于其中心的表面特性的可能性。当前使用商业上使用的铝纸的示例包括：用于热交换器的悬挂板和一系列Al-Clad系列航空合金。目前，这些包裹是通过昂贵的卷粘结技术生产的，从而在高压下将两张纸卷在一起以创建包裹纸。 该研究计划将创建和开发一系列包装铝板产品，并衡量这些包裹产品如何应对工业相关的热机械处理，例如均质化，热/冷滚动和最终热处理。特别是将重点放在理解这些系统中界面附近的冶金反应以及在制造过程中跨界面上溶质的相互作用。
