This research, to be undertaken as a collaboration between Ford, Promatek Research Centre (Magna) and the Universities of Waterloo and Guelph, will address the hot stamping and final properties of a new ultra high strength steel alloy, Usibor 2000-AS. This alloy has a strength of 2,000 MPa making it attractive for automotive anti-intrusion structural applications relative to current 1,500 MPa strength alloys. However, the current lack of process models and characterization data for this alloy represents a barrier to commercial adoption. Thus, a hot stamping process model will be developed to support process and product design and optimization that will include characterization data and sub-models of: (i) heat transfer, coating and substrate evolution within the large-scale (100 m) roller hearth furnaces used in this process; and (ii) constitutive behaviour and formability during high temperature forming (500-850 Celsius). The developed process models and data will enable product weight reduction by fully utilizing the material capabilities, resulting in structural part thickness reductions to 1.0 mm. With up to 40% of car body structural parts projected to be hot stamped, the improved simulation models and process efficiencies from this project will contribute to sustain and potentially increase Ford and Magna's market share in the very large automotive structural market. Competitive technological advantage stemming from this project will secure manufacturing jobs in Canada and the highly qualified students to be trained will establish future innovation capacity. Lighter, safer, more fuel efficient vehicles will be built in Canada and driven around the world.

这项研究将作为福特，Progratek Research Center（Magna）与滑铁卢大学和圭尔夫大学之间的合作进行，将介绍新的超高强度钢合金的热冲压和最终特性，USIBOR 2000-AS。该合金的强度为2,000 MPa，使其对汽车抗注入结构应用具有吸引力，相对于当前的1,500 MPa强度合金。但是，目前缺乏该合金的过程模型和表征数据代表了商业采用的障碍。因此，将开发一个热冲压工艺模型来支持过程，产品设计和优化，其中包括：（i）在此过程中使用的大规模（100 m）辊炉中的热传递，涂料和底物演化的子模型； （ii）高温形成期间的构型行为和形成性（500-850摄氏）。开发的工艺模型和数据将通过充分利用材料功能来减少产品重量，从而导致结构零件厚度降低至1.0毫米。高达40％的汽车结构零件预计将被热盖，因此改进的模拟模型和该项目的流程效率将有助于维持和潜在地增加福特和麦格纳在非常大的汽车结构市场中的市场份额。该项目所带来的竞争性技术优势将确保加拿大的制造业工作，并且受过培训的高素质学生将确立未来的创新能力。更轻，更安全，更高效的车辆将在加拿大建造，并在世界各地驱动。
