NON-TECHNICAL DESCRIPTION: A multi-year international research program is under-way between materials research groups from the University of Missouri - Rolla (UMR), the Universidade Federal do Sao Carlos of Sao Carlos, Brazil (UFSCar), and the Centro Atomico Bariloche of the Comision Nacional Energia Atomico of San Carlos de Bariloche, Argentina (CNEA). The program will focus on the characteristics of iron phos-phate-based glasses and melts. These glasses are of interest for high-level nuclear waste fixation, bioresorbable medical implants, and several other uses. Cooperative research will investigate the resistance to crystallization, corrosion resistance, and response to irradiation of these glasses. The program will also involve the interchange of American and Brazilian students, who will conduct research at both institutions as well as partici-pating in educational opportunities.TECHNICAL DETAILS: At UFSCar, the crystallization kinetics of these glasses will be measured, using a series of new thermal-analysis techniques developed at UMR and UFSCar. At CNEA the corrosion resistance of these glasses will be measured in a variety of fluids, and the glasses will be irradiated. The impact of irradiation on glass properties will be assessed at UFSCar (crystallization kinetics), UMR (structure), and CNEA (corrosion, structure). At UMR, an investigation of phase equilibria in these systems will de-termine liquidus temperatures and equilibrium crystalline phases. The exchange of personnel will allow students and faculty alike to learn research techniques developed at each institution.This work is jointed supported by the Office of International Science and Engineering and the Division of Materials Research.

NON-TECHNICAL DESCRIPTION: A multi-year international research program is under-way between materials research groups from the University of Missouri - Rolla (UMR), the Universidade Federal do Sao Carlos of Sao Carlos, Brazil (UFSCar), and the Centro Atomico Bariloche of the Comision Nacional Energia Atomico of San Carlos de Bariloche, Argentina (CNEA). 该计划将重点介绍基于磷的铁玻璃和融化的特征。 这些眼镜对于高水平的核废料固定，可生物吸收的医疗植入物以及其他几种用途都很感兴趣。 合作研究将研究对这些玻璃的结晶，耐腐蚀性以及对这些玻璃照射的反应的抵抗力。 该计划还将涉及美国和巴西学生的互换，他们将在机构进行研究，并参与教育机会的参与。技术细节：在UFSCAR，这些眼镜的结晶动力学将使用在UMR和UFScar开发的一系列新的热分析技术来测量这些眼镜的结晶动力学。 在CNEA时，这些玻璃的耐耐药性将在多种流体中测量，并将照射玻璃。 辐照对玻璃性能的影响将在UFSCAR（结晶动力学），UMR（结构）和CNEA（腐蚀，结构）上进行评估。 在UMR时，对这些系统中相位平衡的研究将脱离液态液体温度和平衡晶体相。 人员的交流将允许学生和教职员工学习在每个机构开发的研究技术。这项工作是由国际科学与工程办公室和材料研究部门的支持。
