GOALI: Steels for the Next Generation Automobiles

该项目研究的是具有高强度和延展性的TRIP钢的表面氧化工艺，这些钢有望成为未来汽车应用的薄板形式的选择。拟议的研究包括独一无二的应用共聚焦扫描激光显微镜对氧化过程进行原位可视化。一个主要的目标是能够识别氧化物起始的微结构位置，并表征氧化物生长过程中的形态变化。CMU与美国钢铁技术中心(宾夕法尼亚州门罗维尔)和伯利恒钢铁荷马研究实验室(伯利恒)的钢铁工业研究人员之间的密切合作，将通过将材料性能的元素整合到现有的加工、结构和性能培训中，扩大材料研究生的培训。这将给学生提供一个机会，让他们了解工业环境中各种上游和下游钢铁制造步骤。研究生培训预计将导致对现代制造业中衡量材料性能的标准的认识。通过“材料加工”和“运输与动力学”课程，将与产业界的合作努力融入到CMU的教学中，其中包括对工业现场的实地考察。

The project research is on the surface oxidation process on TRIP steels with high strength and ductility that are expected to be the future choices for automotive applications in the form of thin sheets. The proposed investigation includes unique application of confocal scanning laser microscope for in-situ visualization of the oxidation process. A major goal is to be able to identify microstructural sites where the oxides initiate, and characterize the morpholigical changes during oxide growth. Results from the high-temperature studies will be combined with room temperature characterization of the scale and steel chemistries and structures in developing analytical models.The close collaboration between CMU and steel industrial researchers at US-Steel Technical Center (Monroeville, PA) and Bethlehem Steel Homer Research Laboratory (Bethlehem, PA), will broaden the training of materials graduate students by integrating elements of materials performance into the existing training in processing, structure and properties. This will give an opportunity to expose students on the various up and down stream steel manufacturing steps in industrial environments. The graduate student training is expected to result in an awareness of the criteria by which materials performance is judged in the modern manufacturing industry. Distinct plans are outlined to incorporate the collaborative efforts with industry into teaching at CMU through courses on 'Materials Processing' and 'Transport and Kinetics' that would include field trips to industrial sites.
