The Center for Advanced Non-Ferrous Structural Alloys (CANFSA) at Iowa State University (ISU) consists of students, post-docs and faculty who work with their CANFSA counterparts at the Colorado School of Mines (Mines) to engage scientists and engineers from both industry and government laboratories to discover fundamental understandings of the physical and mechanical metallurgy of non-ferrous alloys (i.e., alloying and processing effects on microstructure, properties and performance). The motivation for CANFSA is to address the national decline in the training of students in this area that is critical to U.S. dominance in high performance materials, structures and advanced manufacturing. Today, there are only a few universities remaining who train students in these core science and engineering areas that are so critical to our industries, especially as National investments are made in new advanced materials and manufacturing strategies. In fact, these declines have greatly reduced
 the synergies that existed previously between faculty, students, and the relevant industries, and this, in turn, has significantly weakened the technical dominance of US industries that rely heavily
 on these materials. CANFSA was organized to counter this trend by conducting fundamental scientific studies on these advanced materials and their manufacturing, thereby filling this workforce development gap and simultaneously contributing to U.S. global industrial competitiveness.The objective of CANFSA is to conduct basic and applied physical metallurgy 
research of direct relevance to the industries that develop, manufacture and use advanced 
non-ferrous structural alloys, and to train students in these important subjects. This is accomplished by engaging students in topics of importance to industry and government labs, and to have both faculty members and external mentors guide the students' fundamental research. The specific details of the projects that are conducted within the Center vary as topics are selected that have the most direct relevance for the partners from industry and the national laboratories. To date, the Center has conducted leading research in the areas of: thermal and mechanical processing of non-ferrous alloys (e.g., 3rd Generation Al-Li alloys, texture anisotropy of Ti-6Al-4V); ultrafine grained alloys and their mechanical behavior (e.g., Ti and Mg); aging of high-strength beta-Ti alloys; processing of microeutectic Al alloys; microstructural evolution (e.g., Ni-Ti-Hf intermetallics, Ni-based superalloys, high entropy alloys); multi-layer coatings; lube-free die casting; and the role of trace elements and small microstructural variations on mechanical properties. To conduct these varied research projects and accomplish the goals of the Center, faculty members with complementary 
expertise in the areas of theory, modeling, processing and characterization are working together with members from industry and government laboratories. Iowa State University has a variety of processing, characterization, and computational tools available on which to conduct the Center?s research. This includes state-of-the-art electron microscopy and atom probe capabilities in a newly established Sensitive Instrumentation Facility and elsewhere across ISU's campus. In addition, researchers have access to a variety of advanced processing equipment and computational tools that span across a wide range of methods, including: atomistic simulation techniques; discrete dislocation dynamics; phase field simulation; cellular automata; finite element methods and FFT-based simulation approaches. Computations can be made ranging from fundamental physical processes to macroscale fluid and heat transfer. This expertise at ISU is complementary to that at CSM, and collectively, CANFSA is able to offer a suite of unique capabilities to its membership.

爱荷华州州立大学（ISU）的先进有色金属结构合金中心（CANFSA）由学生，博士后和教师组成，他们与科罗拉多矿业学院（矿业）的CANFSA同行合作，让来自工业和政府实验室的科学家和工程师参与，以发现对有色金属合金物理和机械冶金的基本理解（即，合金化和加工对微观结构、性质和性能的影响）。CANFSA的动机是解决全国学生在这一领域的培训下降，这对美国在高性能材料，结构和先进制造业的主导地位至关重要。今天，只有少数几所大学在这些对我们的行业至关重要的核心科学和工程领域培养学生，特别是在国家投资于新的先进材料和制造战略的情况下。事实上，这些下降大大减少了
教师、学生和相关行业之间以前存在的协同作用，这反过来又大大削弱了严重依赖这些材料的美国行业的技术优势&。CANFSA的成立旨在通过对这些先进材料及其制造进行基础科学研究来应对这一趋势，从而填补这一劳动力发展差距，同时为美国的全球工业竞争力做出贡献。CANFSA的目标是进行与开发，制造和使用先进有色金属结构合金的行业直接相关的基础和应用物理冶金#8232;研究，并培养这些重要学科的学生。这是通过让学生参与对行业和政府实验室重要的主题来实现的，并让教师和外部导师指导学生的基础研究。在该中心内开展的项目的具体细节各不相同，因为选择的主题与来自工业界和国家实验室的合作伙伴最直接相关。迄今为止，该中心在以下领域进行了领先的研究：有色合金的热加工和机械加工（例如，第三代Al-Li合金，Ti-6Al-4V的织构各向异性）;超细晶粒合金及其机械行为（例如，Ti和Mg）;高强度β-Ti合金的时效;微共晶Al合金的加工;微观结构演变（例如，Ni-Ti-Hf金属间化合物、Ni基高温合金、高熵合金）;多层涂层;无润滑压铸;以及微量元素和微小微观结构变化对机械性能的作用。为了进行这些不同的研究项目，并实现中心的目标，教师与互补
在理论、建模、加工和表征领域的专业知识正在与来自工业和政府实验室的成员合作。爱荷华州州立大学有各种各样的处理，表征和计算工具，可用于进行中心？的研究。这包括在新建立的敏感仪器设施和ISU校园其他地方的最先进的电子显微镜和原子探针能力。此外，研究人员还可以使用各种先进的处理设备和计算工具，这些设备和工具涵盖了各种方法，包括：原子模拟技术;离散位错动力学;相场模拟;元胞自动机;有限元方法和基于FFT的模拟方法。计算可以从基本的物理过程到宏观尺度的流体和热传递。ISU的这一专业知识与CSM的专业知识相辅相成，总的来说，CANFSA能够为其成员提供一套独特的能力。
