9507577 Weertman This U.S.-Mexico award will support Prof. Julia Weertman of Lorthwestern University in a research collaboration with Profs. Jorge Cabanas Moreno and Hector Calderon Benavides of the Instituto Politecnico Nacional (IPN) in Mexico City, for research on the mechanical behavior and characterization of nanocrystalline metals, and the kinetics of coarsening of coherent particles in nickel and iron-based alloys. In studying the mechanical properties and internal structure of nanocrystalline metals, samples will be prepared by mechanical alloying/mechanical milling and two other synthesis routes. Thus the influence of preparation method on properties and grain boundary behavior will be examined. The coarsening behavior of coherent particles in metal alloys will be studied as a function of lattice mismatch in samples containing bimodal particle distributions. The proposed research collaboration will benefit from the extensive experience at Northwestern University on the mechanical properties and internal structure of nanocrystalline materials and the synthesis and processing routes followed by the Mexican side. This award will also facilitate the travel of students, thus providing them with an international research experience early in their careers. ***

9507577 Weertman 该美国-墨西哥奖项将支持洛思威大学的 Julia Weertman 教授与 9507577 Weertman 教授的研究合作。墨西哥城国立理工大学 (IPN) 的 Jorge Cabanas Moreno 和 Hector Calderon Benavides，研究纳米晶金属的机械行为和表征，以及镍基和铁基合金中相干颗粒的粗化动力学。 在研究纳米晶金属的机械性能和内部结构时，将通过机械合金化/机械铣削和其他两种合成路线来制备样品。 因此，将检查制备方法对性能和晶界行为的影响。 将研究金属合金中相干颗粒的粗化行为，作为包含双峰颗粒分布的样品中晶格失配的函数。 拟议的研究合作将受益于西北大学在纳米晶材料机械性能和内部结构以及墨方遵循的合成和加工路线方面的丰富经验。 该奖项还将方便学生的旅行，从而为他们在职业生涯的早期提供国际研究经验。 ***
