This award from the U.S.-Argentina Cooperative Science Program supports research in materials science to be conducted by Dr. Diana Farkas of Virginia Polytechnic Institute in collaboration with Dr. E.J. Savino and Dr. R. Pasianot of the National Atomic Energy Commission (CNEA) of Argentina. The goal of the project is to carry out computer simulation of defect structure in intermetallic alloys. The project continues an active collaboration in the area of theoretical models for radiation - enhanced diffusion. The project focuses on the development of empirical potentials of many body type suitable for computer simulation of extended defects in ordered alloys. These interatomic potentials will be applied to the simulation of point defects in pure metals and alloys and extended defects (grain boundaries and dislocations) in pure metals and in alloys and the interaction of these two types of defects. ***//

该奖项由美国-阿根廷合作科学计划资助，支持弗吉尼亚理工学院的 Diana Farkas 博士与 E.J.阿根廷国家原子能委员会 (CNEA) 的 Savino 和 R. Pasianot 博士。 该项目的目标是对金属间合金中的缺陷结构进行计算机模拟。 该项目继续在辐射增强扩散理论模型领域进行积极的合作。 该项目的重点是开发适合有序合金中扩展缺陷的计算机模拟的多种体类型的经验潜力。 这些原子间势将应用于模拟纯金属和合金中的点缺陷以及纯金属和合金中的扩展缺陷（晶界和位错）以及这两类缺陷的相互作用。 ***//
