This project involves an interdisciplinary interaction between researchers with expertise in tribology, materials, and precision engineering. Bulk metallic glasses are materials that may permit the mass production of high strength micro-components of arbitrary geometry at extremely low cost. The successful development of micro-molding technology with these materials will revolutionize micro-systems and enable numerous wholly new classes of micro-devices. The PIs have shown that certain bulk metallic glasses can be molded to produce micron sized or potentially sub-micron sized features at low temperatures (350C-400C), and retain their high strengths. The ability to flow the bulk metallic glasses in the supercooled liquid state appears to be ideally suited for mass production using a micro-molding process.During the project, the material properties relevant to processing of bulk metallic glasses will be characterized. This will be used to determine the processing parameters for forcing this metal glass into molds for micro-components. Accuracy of molded micro-component features will be assessed using an embossing technique with three primary processing parameters varied: pressure, temperature, and embossing rate. As part of this project, some of the undergraduate students in the Integrated Product and Process Design (IPPD) group will work on the design of specific devices and systems. The IPPD students are from 7 different engineering and business departments and typically work on industry-submitted projects. The University of Florida has one of the largest populations of Latino students, and the PIs intend to utilize the close interaction in the IPPD program to recruit these minority students into research and the graduate program. At the conclusion of this project, a knowledge base will have been created to enable a whole new class of products with applications in a wide range of micro and meso-scale systems.

该项目涉及具有摩擦学，材料和精确工程专业知识的研究人员之间的跨学科互动。散装金属眼镜是可以允许以极低成本的任意几何形状的高强度微型组件的大量生产的材料。 这些材料成功开发了微型焊接技术，将彻底改变微型系统，并使许多全新的微型设备能够彻底发展。 PIS表明，可以在低温（350C-400C）下生产某些散装金属玻璃，以产生微米尺寸或潜在的亚微米尺寸特征，并保留其高强度。在超冷液态中流动散装金属玻璃的能力似乎非常适合使用微型焊接过程。在项目中，将表征与散装金属玻璃处理的材料特性。 这将用于确定将这种金属玻璃迫使微型组件的模具迫使该金属玻璃的加工参数。模制微分特征的精度将使用带有三个主要处理参数的压花技术评估：压力，温度和压花速率。 作为该项目的一部分，集成产品和过程设计（IPPD）小组中的一些本科生将致力于特定设备和系统的设计。 IPPD的学生来自7个不同的工程和商业部门，通常从事行业的项目。佛罗里达大学是拉丁裔学生中最大的人群之一，PIS打算利用IPPD计划中的密切互动将这些少数族裔学生招募到研究和研究生课程中。在该项目的结论结束时，将创建知识库，以启用具有各种微型和中尺度系统应用程序的全新产品类别。
