U.S.-Indonesia Planning Visit: Use of Neutron Diffraction

0721417 Fergus该奖项支持计划访问，使亚拉巴马奥本大学的Jeffrey费尔格斯教授能够与印度尼西亚科学研究所（LIPI）的Leonardus Kardono博士、印度尼西亚国家核能机构的Ridwan博士和印度尼西亚大学的Bambang Soegijono博士会面。 他们的目标是建立一个合作项目，研究氢和水蒸气对氧化铬形成合金氧化的影响，这些合金用作固体氧化物燃料电池（SOFC）中的互连材料。 这是一个重要的科学和实践问题，但尚未完全理解。 在SOFC互连中，由于合金同时暴露于具有不同氧和氢分压的不同气氛中，因此问题特别复杂。 在所提出的工作中，仔细和系统地控制和测量氧化过程中的氢将提高对这一复杂现象的理解。 奥本大学和印度尼西亚各机构的研究人员之间有着充分的共同利益，表明他们能够成功地开展拟议的活动，这种互动将使双方受益。 对这些相互作用的进一步理解是一项重要的科学贡献，也可用于解决固体氧化物燃料电池和氧化铬形成合金的其他高温应用开发中的实际问题。 此外，所开发的技术可应用于评估水蒸气对其他合金系统的氧化行为的影响。 这次访问还将为两名本科生提供支持。 这种全球研究经验可能会为他们提供许多机会，在他们的研究生涯中与他们的印度尼西亚同事继续接触。 该奖项由数学和物理科学理事会材料研究部共同资助。

0721417FergusThis award supports a planning visit to enable Professor Jeffrey Fergus at Auburn University in Alabama to meet with Dr. Leonardus Kardono at the Indonesian Institute of Sciences (LIPI), Dr. Ridwan at the Indonesia National Nuclear Energy Agency and Dr. Bambang Soegijono at the University of Indonesia. Their goal is to establish a collaborative project to investigate the effect of hydrogen and water vapor on the oxidation of chromia-forming alloys for use as interconnect materials in solid oxide fuel cells (SOFCs). This is an important scientific and practical issue, which is not completely understood. In SOFC interconnects, the issue is particularly complicated as the alloys are simultaneously exposed to different atmospheres with different oxygen and hydrogen partial pressures. The careful and systematic control and measurement of hydrogen during oxidation in the proposed work will improve understanding of this complicated phenomenon. There is sufficient overlap of interests between researchers at Auburn University and the Indonesian Institutions to indicate that they can successfully pursue the activities proposed, and that the interaction will benefit both sides. Improved understanding of these interactions is an important scientific contribution that can also be used to address practical problems in the development of solid oxide fuel cells and other high-temperature applications of chromia-forming alloys. In addition, the techniques developed can be applied to the evaluation of the effects of water vapor on the oxidation behavior of other alloy systems. The visit will also provide support for two undergraduate students. This global research experience will likely provide them many opportunities for continuing contacts with their Indonesian colleagues throughout their research careers. This award is co-funded with the Division of Materials Research in the Directorate for Mathematical and Physical Sciences.
