MRI: Development of a Multi-Scale Thermal-Mechanical-Spectroscopic System for in-Situ Materials Characterization, Research, and Training

这一重大研究仪器奖支持中佛罗里达大学(UCF)开发多尺度热-机械-光谱系统(TMS)，用于现场材料表征、研究和培训。该仪器将支持在多种长度刻度、压力、机械载荷和温度范围内同时进行热、机械和光谱(TMS)测量。该仪器将能够准确评估和预测材料/器件在真实世界操作条件下的行为，研究变形微观力学，监测结构变化和预测寿命，并在宏观/微观长度尺度上表征材料。该仪器非常适合在现实条件下捕捉以前无法接触到的材料行为方面。这种仪器的开发将产生一种革命性的工具，有可能展示新的研究成果，同时跨越能源(例如透平机械)、民用基础设施(例如桥梁)、国防(例如高性能飞机、装甲)的广泛应用。该项目提供了对博士后、研究生和本科生进行点对点学习和指导的机会，这些学生将参与构建子系统并将其整合到仪器中。接触仪器开发和与最先进的设备的集成将加强学生在理论设计的实际应用方面的教育，为他们提供高端仪器设计过程的经验，并扩大他们的研究重点，考虑现场技术，以扩大现有的研究领域，并导致新的研究领域。开发的系统将在UCF上供用户使用。*材料和部件的初始和不断演变的机械性能知识对于检测可能导致灾难性故障的不良裂纹扩展、相变、纹理、微裂纹或其他结构/几何不稳定性是必不可少的，尤其是在部件运行时。开发一种支持多个长度尺度、压力、机械载荷和温度的同时热-机械-光谱(TMS)测量的仪器，将首次使获得此类知识的能力成为可能，因为材料是在接近运行条件下进行现场评估的。该奖项来自主要研究仪器项目，用于支持中佛罗里达大学TMS系统的开发。奥兰多中佛罗里达大学开发的用于在不同环境中的室温或高温复杂加载条件下对不同长度尺度的材料进行现场结构表征和测试的系统将在奥兰多的中佛罗里达大学提供。该项目将吸引学生和博士后，他们将成为下一代仪器开发人员。

This Major Research Instrumentation award supports the University of Central Florida (UCF) with the development of a Multi-Scale Thermal-Mechanical-Spectroscopic System (TMS) for in-situ materials characterization, research, and training. The instrument will support simultaneous thermal, mechanical, and spectroscopic (TMS) measurements over multiple length scales, pressures, mechanical loads, and temperatures. The instrument will enable accurate assessment and prediction of material/devices behavior under real-world operating conditions, studies of deformation micromechanics, monitoring structural changes and predicting lifetime, to characterizing materials over macro-/micro-length scales. The instrument will be ideal for capturing previously inaccessible aspects of material behavior under realistic conditions. This instrument development will result in a revolutionary tool with the potential to present new research findings, while spanning a wide range of applications in energy (e.g., turbomachinery), civil infrastructure (e.g., bridges), defense (e.g., high-performance aircrafts, armor). The project presents opportunities for peer-to-peer learning and mentoring of postdocs, and graduate and undergraduate students who will participate in building subsystems and integrating them into the instrument. The exposure to instrument development and integration with a state of the art equipment will enhance the education of the students in practical applications of theoretical designs, provide them with the experience of the design process for high-end instrumentation and expand their research focus to consider in situ techniques to expand existing research areas and lead to new fields of research. The developed system will be available to users at UCF.****Knowledge of initial and evolving mechanical properties of materials and parts is indispensable to detect undesirable crack growth, phase transitions, texturing, microcracking or other structural/geometrical instabilities that can lead to disastrous failure, particularly when components are in operation. The development of an instrumentation that supports simultaneous thermal-mechanical-spectroscopic (TMS) measurements over multiple length scales, pressures, mechanical loads, and temperatures will, for the first time, enable the capability to achieve such knowledge, as materials are evaluated in-situ under near-operational conditions. This award from the Major Research Instrumentation program supports the University of Central Florida with the development of a TMS system. The developed system for in-situ structural characterization and testing of materials on the various length scales under complex loading conditions at room or elevated temperatures in different environments will be available at the University of Central Florida, Orlando. The project will engage students and postdocs who will become the next generation of instrument developers.
