U.S.- Korea Cooperative Research: Directional Transformation of High-Temperature Alloys

0325940 Trivedi该奖项促进了爱荷华州州立大学的Rohit Trivedi教授和韩国昌原国立大学的Jehyun Lee教授在高温合金方面的合作研究。 他们正在研究影响由铁、铬和铝的各种组合组成的合金的固态转变和微观结构的工艺变量。 这两个研究小组拥有独特和互补的专业知识和设施。爱荷华州集团将生产在韩国加工的合金锭，并将负责理论模型的开发和一些材料表征。大多数实验工作将在韩国使用昌原大学最先进的定向凝固设备进行，该设备可以将样品加热到比爱荷华州州立大学的设备高出几百摄氏度。 这两个小组拥有互补的光学和电子显微镜设备，以各种方式检查产生的材料结构，两位研究人员将共同分析数据。更广泛的影响学生的培训和研究经验是项目计划的重要组成部分。一名美国研究生将获得国际研究经验，并在韩国实验室获得爱荷华州无法获得的设备，然后将有助于在爱荷华州建造类似的设备。 该项目还包括一名本科生在访问爱荷华州期间与韩国调查员一起获得研究经验的计划。从这项研究中获得的结果将是有意义的钢铁工业，因为它们是相关的合金和加工方法的设计和加工不锈钢的改进选择。

0325940TrivediThis award facilitates collaborative research on high temperature alloys between Professor Rohit Trivedi of Iowa State University and Professor Jehyun Lee of Changwon National University in Korea. They are examining processing variables that affect the solid-state transformation and microstructure of alloys composed of various combinations of Iron, Chromium and Aluminum. The two research groups have unique and complimentary expertise and facilities. The Iowa State group will produce the alloy ingots for processing in Korea and will be responsible for the development of the theoretical model and for some of the materials characterization. Most experimental work will be carried out in Korea using state of the art directional solidification apparatus at Changwon University that can heat the samples several hundred degrees Celsius higher than the equipment at Iowa State University. The groups have complementary optical and electron microscopy equipment to examine the resulting material structure in various ways, and the two investigators will analyze the data jointly. Broader ImpactsTraining and research experience of students is an important part of the project plan. An U.S. graduate student will obtain international research experience and access to equipment in the Korean Lab that is not available at Iowa State, and will then contribute to constructing comparable equipment at Iowa State. The project also includes plans for an undergraduate student to gain research experience with the Korean investigator during his visit to Iowa State. The results obtained from this study will be of significance to steel industries because they are relevant to improved selection of alloys and processing approaches for the design and processing of stainless steels.
