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

0325940trivedi该奖项促进了爱荷华州立大学教授Rohit Trivedi和昌原大学教授Jehyun Lee在高温合金领域的合作研究。他们正在研究影响铁、铬和铝的各种组合组成的合金的固态转变和微观结构的加工变量。这两个研究小组拥有独特和互补的专业知识和设施。爱荷华州立集团将生产合金锭，在韩国进行加工，并将负责理论模型的开发和一些材料的表征。大部分实验工作将在国内进行，利用昌原大学最先进的定向凝固设备，该设备比爱荷华州立大学的设备加热样品高出数百摄氏度。这两个小组有互补的光学和电子显微镜设备，以各种方式检查所得的材料结构，两位研究人员将共同分析数据。学生的广泛影响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，并获得在爱荷华州立大学没有的韩国实验室的设备，然后将为在爱荷华州立大学建造类似的设备做出贡献。该项目还包括让一名本科生在访问爱荷华州的韩国研究员那里获得研究经验的计划。从本研究中获得的结果将对钢铁工业具有重要意义，因为它们与不锈钢设计和加工的合金选择和加工方法的改进有关。

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.
