Knowledge based processing of novel clad/laminate metallic systems

加拿大在21世纪面临的最重大的全球挑战之一是继续在竞争激烈的初级金属开采和加工部门保持强大的经济地位。为了让加拿大继续在这一领域发挥全球领导作用，开发先进金属系统的新颖和最先进的制造技术是势在必行的。拟议的研究计划将继续建立在申请人在实验测量和开发先进金属产品和制造工艺的基于知识的工艺模型方面的研究专长领域。本节目将重点介绍通过共铸生产的新型复合金属系统。第一次，通过共铸生产的复合金属薄板创造了以经济高效的方式相对于其中心来裁剪薄板的表面属性的可能性。目前商业上使用的覆层铝板的例子包括：热交换器的铜焊薄板和航空航天合金的覆铝系列。目前，这些复合板是通过昂贵的滚压粘合技术生产的，通过这种技术，两个薄板在高压下轧制在一起，形成复合板。这项研究计划将创建和开发一系列覆层铝板产品，并测量这些覆层产品对工业上相关的热机械处理(如均质化、热/冷轧和最终热处理)的反应。特别强调了解在这些系统中靠近界面发生的冶金反应，以及在制造操作过程中跨越界面的溶质相互作用。

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.
