U.S.-France Cooperative Research: Surface Properties of Quasicrystals and Quasicrystalline Alloys

这个为期两年的奖项为美法合作研究各种类型的多晶准晶体（无论是块状还是涂层）的生产和表征提供了支持。 此次合作涉及由爱荷华州立大学艾姆斯实验室的 Alan I. Goldman 和法国南锡矿业学院的 Jean-Marie Dubois 领导的美国和法国研究小组。 研究人员将合成一些新型二十面体合金并研究它们的结构和表面特性。 美国研究小组为此次合作带来了准晶合金和涂层的加工和表征以及表面化学方面的专业知识。 这家法国集团在样品制备和准晶合金机械性能方面的专业知识对此进行了补充。 该项目加深了人们对准晶体作为新型摩擦学和强度增强材料潜力的认识。

This two-year award provides support for US-France cooperative research on the production and characterization of various types of polygrained quasicrystals, either as bulk pieces or as coatings. The collaboration involves the US and French research groups led by Alan I. Goldman at Iowa State University's Ames laboratory and Jean- Marie Dubois at the Ecole des Mines in Nancy, France. The investigators will synthesize a number of new icosahedral alloys and study their structural and surface properties. The US research group brings to this collaboration expertise on processing and characterization of quasicrystalline alloys and coatings, and surface chemistry. This is complemented by the French group's expertise in sample preparation and mechanical properties of quasicrystalline alloys. The project advances understanding of the potential of quasicrystals as a new class of tribolological and strength-enhancing materials.
