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

这项为期两年的奖项为美法合作研究各种多晶准晶的生产和表征提供了支持，这些准晶可以是块状或涂层。由爱荷华州立大学艾姆斯实验室的艾伦·I·戈德曼和法国南希矿业学院的Jean-Marie Dubois领导的美国和法国研究小组参与了这一合作。研究人员将合成一些新的二十面体合金，并研究它们的结构和表面性质。这家美国研究小组将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带到了这次合作中。此外，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也起到了补充作用。该项目促进了人们对准晶作为一类新的摩擦学和强度增强材料的潜力的理解。

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.
