FRG: Fundamental Approaches to Design of New Structural Magnesium Alloys

该基金研究了凝固、相平衡和变形机制的基本方面，以便为未来高温镁系统的设计奠定基础。研究了两个四元系(Mg-Al-Ca-Sr和Mg-Al-Ca-Ce)的相平衡和微观偏析，然后利用常规显微镜和高分辨率应变图谱技术进行高温变形。铸造试验将在福特汽车公司和Eck工业公司的铸造设施中进行。计算热力学和相平衡将用于优化合金成分。一个主要的目标是建立一个有效的实验和计算的组合，以加速复杂结构合金系统中的合金设计。这项研究是密歇根大学、威斯康星大学和福特汽车公司的合作项目。拨款用于开发新的高温结构镁合金，用于交通行业，在交通行业中，减轻车辆重量是实现更高性能和燃油效率的关键因素。拟议研究的一个重要目标将是在美国开展更集中的高温铸造镁合金研究工作，并提供研究活动的核心，培训学生和博士后研究人员镁合金设计的基础知识。除此之外，该计划还将为参加由密歇根大学主办、ASM国际、SAE和矿物金属与材料协会赞助的高中科学教师夏令营的机械工程师和高中教师开发一个关于镁的教育模块。

The grant investigates fundamental aspects of solidification, phase equilibria and deformation mechanisms in order to establish a foundation for the design of future high temperature magnesium systems. Phase equilibria and microsegregation will be studied in two quaternary systems, Mg-Al-Ca-Sr and Mg-Al-Ca-Ce, followed by high temperature deformation using conventional microscopy along with high-resolution strain mapping techniques. The casting experiments will be made at casting facilities at Ford Motor Company and Eck Industries Inc. Computational thermodynamics and phase equilibria will be used to optimize the alloy compositions. A major goal is to structure an efficient combination of experiments and computation to accelerate alloy design in complex structural alloy systems. The research is a collaborative program between the University of Michigan, University of Wisconsin and the Ford Motor Company.The grant allows an effort to develop new high temperature structural magnesium alloys for transportation industry applications, where vehicle weight reduction is a critical element of achieving greater performance and fuel efficiency. An important goal of the proposed research will be to develop in the United States a more concentrated research effort on high temperature cast magnesium alloys and to provide a nucleus of research activity that will train students and postdoctoral fellows in the fundamentals of magnesium alloy design. Beyond this, the program will also develop an educational module on Mg for mechanical engineers and high school teachers participating in a summer camp for high school science teachers hosted by the University of Michigan and sponsored by ASM International, SAE and the Minerals Metals and Materials Society.
