There is a growing need to develop innovative steel-based solutions that can meet the growing infrastructure challenges across Canada. There are presently several major government and private-sector initiatives that require the development of novel steel plates with excellent strength and toughness. Some of these initiatives include the modernization of the Canadian Navy and the construction of oil and gas pipelines. Nowhere is the pressure to develop novel steels more apparent than in the automotive industry. The push to develop new steels has resulted in important changes in steel compositions. The impact of these composition changes on the thermo-mechanical processing of AHSS has yet to be explored. The aim of the present project is to develop a physically-based model for the hot-rolling of novel low alloy steels that contain alloying additions beyond the traditionally used range. Fundamental studies will be carried out on the interaction of alloying elements at moving boundaries and on precipitate evolution during hot rolling. The results of these fundamental studies will be integrated into a robust multi-pass precipitation model that predicts grain-size evolution, precipitation hardening and flow stress changes. The model will be linked to a widely used commercial mill-load prediction software package in order to accurately predict mill loads during hot rolling. This work will be carried out in close collaboration with the industrial partners and will ultimately allow EVRAZ Inc. N.A. and Stelco (two of Canada's leading steel produces) to optimize the chemistry and thermomechanical processing parameters of the steels produced at their facilities in Regina and Lake Erie. The new steels will allow Stelco to extend its market share in the automotive sheet sector. It would also allow EVRAZ to produce a wide range of competitive product for the oil and gas industry. In total, 1 PhD student, 2 MSc students and one Research Associate will be trained as part of this grant.

越来越需要开发基于创新的钢铁解决方案，以应对加拿大越来越多的基础设施挑战。 目前，有几项主要的政府和私营部门倡议需要以极好的力量和韧性开发新型钢板。 其中一些举措包括加拿大海军的现代化以及石油和天然气管道的建设。在汽车行业中，开发新颖的钢的压力没有任何地方。 开发新钢的推动导致钢质成分的重要变化。 这些组成变化对AHSS热力学处理的影响尚未探索。 本项目的目的是开发一个基于物理的模型，用于对新型低合金钢进行热卷，该模型含有传统使用范围以外的合金添加。 基本研究将对在热滚动过程中移动边界和降水进化时合金元素的相互作用进行基本研究。 这些基本研究的结果将集成到一个可靠的多通降水模型中，该模型可以预测晶粒大小的演化，降水硬应力变化和流动应力的变化。 该模型将链接到广泛使用的商业磨坊载荷预测软件包，以便在热滚动过程中准确预测磨机负载。 这项工作将与工业合作伙伴密切合作进行，并最终允许Evraz Inc. N.A.和Stelco（加拿大领先的钢铁生产的两个），以优化其在Regina和Lake湖设施中生产的钢的化学和热机械加工参数伊利。 新的钢将允许Stelco扩大其在汽车部门的市场份额。 这也将使Evraz为石油和天然气行业生产广泛的竞争产品。 总共有1名博士生，2名MSC学生和一名研究助理将作为这笔赠款的一部分进行培训。
