MRI: Acquisition of an Ultra Rapid Quenching Apparatus for Research and Education

主要研究仪器项目为波多黎各马亚圭斯大学提供了一个尖端的多功能超快速淬火设备（URQA），用于合成具有非晶、亚稳相和微晶结构的材料。URQA将作为一个研究和教育设施而建立，它将支持和加强波多黎各大学mayag<s:1> ez校区和里约热内卢Padias校区在能源转换材料领域快速扩展的研究基础设施和正在进行的多样化和跨学科研究项目。除了为材料采购节省大量成本外，URQA还为三个部门的六名研究人员提供了新的研究方向和多元化领域的教育和培训机会，即材料工程科学，物理和化学，来自两个校区，Mayaguez和里约热内卢Padias。URQA将支持材料科学与工程的新研究生课程，该课程将用于现有课程以及材料工程的新课程。此外，URQA的研究将有利于区域工业的发展。大约15%的仪器操作时间将用于教育和培训。该仪器由无坩埚悬浮熔融组成，这使得它非常适合熔化具有高熔点的活性材料。该仪器还能够达到每秒100万开尔文以上的高冷却速度。材料与材料科学和工程的大多数领域有关。该仪器在波多黎各是独一无二的，对于支持正在进行的多样化和跨学科的研究项目至关重要。拟议的URQA系统支持的具体研究活动包括：(1)包合物材料的合成以及磁性、热电性和超导性的研究；(2)用于航空航天焊接高强度焊丝合成的纳米亚稳体系；(3)纳米复合永磁体的合成与加工；(4)用于生物医学的磁性纳米结构材料；稀土金属间化合物的合成及物理性质。

The Major Research Instrumentation program supports the University of Puerto Rico Mayaguez with the acquisition of a cutting-edge multi-function Ultra Rapid Quenching Apparatus (URQA) for the synthesis of materials with amorphous, metastable phases and microcrystalline structures. URQA will be established as a facility for research and education and it will support and enhance the rapidly expanding research infrastructure in the field of energy conversion materials and on-going diverse and interdisciplinary research projects at the University of Puerto Rico at Mayagüez and Rio Padias campus. In addition to the significant cost saving for material acquisition, the URQA also provides opportunity for new research directions and for education and training in a diverse field by six researchers in three departments, i.e. Materials Engineering Science, Physics and Chemistry from two campuses, Mayaguez and Rio Padias. The URQA will support a new graduate program in Materials Science &amp; Engineering, and it will be used in existing courses, as well as in new courses in materials engineering. In addition, the URQA research will be beneficial for regional industry. Approximately 15% of the instrument operating time will be dedicated to education and training.The instrument consists of a crucible-free levitation melting, which makes it well suited for melting reactive materials bearing high melting points. The instrument is also capable of high cooling rates of more than one million degree Kelvin per second. The materials are relevant to most fields in materials science and engineering. The instrument is unique in Puerto Rico and essential to supporting a diverse and interdisciplinary ongoing research projects. Specific research activities supported by the proposed URQA system include: (1)synthesis of clathrate materials and the study of magnetic, thermoelectric and superconducting properties;(2) nanostructured metastable systems for the synthesis of high strength wires for aerospace welding applications; (3)synthesis and processing of nanocomposite permanent magnets; (4)magnetic nanostructured materials for biomedicine application; and synthesis and physical properties of rare-earth intermetallic compounds.
