Integrated research program for through-process modeling of Al alloys

该研究计划将阐明和联系铝合金板材在整个工业生产过程中组织发展所固有的基本冶金过程，如凝固、金属间化合物颗粒形成、加工硬化和再结晶，包括铸造、均质化、热轧、冷轧和退火。它将在加拿大和国际上独一无二，因为它将结合多种技能和技术，从分子动力学、相场建模和蒙特卡罗模拟到成核和织构演化的热力学模型。该项目的最终目标是将从几个基本微观模型产生的输入、输出和知识自我一致地联系起来，从而提供第一代通过过程建模(TPM)链来研究加工历史对铝合金性能的影响。该项目的一个决定性特点是，研究将在滑铁卢大学和麦克马斯特大学联合进行，利用两所大学的研究专业知识，涵盖轧制铝板生产中涉及的所有上述现象。这项工作将得益于我们的工业合作伙伴Novelis全球技术中心的参与，该中心将专门派出一名TMP专家与大学团队合作，通过将模拟和模型与工业实验和实践进行比较来帮助验证他们的努力。

The proposed research program will elucidate and link the fundamental metallurgical processes such as solidification, intermetallic particle formation, work hardening and recrystallization inherent to microstructure development in aluminum alloy sheet production through the entire industrial manufacturing process, including casting, homogenization, hot rolling, cold rolling and annealing. It will be unique in it scope in Canada and internationally as it will marry a diverse set of skills and techniques, ranging from molecular dynamics, phase field modeling and Monte Carlo simulation to thermodynamic models of nucleation and texture evolution. The ultimate goal of this project is to self-consistently link inputs, outputs and knowledge generated from several fundamental microscopic models, thereby providing a first-generation through process modeling (TPM) chain of the effects of processing history on the properties of aluminum alloys. A defining character of this program is that the research will be undertaken jointly at the University of Waterloo and McMaster University, leveraging research expertise at each University that covers the entire spectrum of aforementioned phenomena involved in rolled aluminum sheet production. This work will benefit from the participation of our industrial partner, Novelis Global technology Centre, which will dedicate a TMP specialist to work with the university team to help validate their efforts by comparing simulations and models against industrial experiments and practices.
