Acquisition of a Transmission Electron Microscope

9311739诺顿这款为华盛顿州立大学提供的现代化、研究级200千伏传输电子显微镜，具有扫描和分析能力，将用于扩大材料研究和教育项目。材料研究已被确定为华盛顿州立大学的一个高度优先的重点领域。最近成立了两个跨学院的组织--材料研究中心和材料科学计划--以解决材料科学的跨学科性质。材料研究中心由19名高级参与者组成，目的是鼓励材料和应用浓缩材料科学领域的合作、跨学科研究项目。材料科学项目是华盛顿州立大学材料科学项目的教育分支。材料科学项目于1990年秋季启动，因此是该大学最新设立的博士项目。这是美国为数不多的真正跨学科的项目之一，因为它涉及到工程学和科学系的积极参与。来自6个系的22名教职员工参加了该项目。该仪器将允许在明场和暗场模式下的常规成像、高空间分辨率成像、电子衍射以及对透射电子显微镜样品的微观结构特征的微观分析。还需要一个加热台和温度控制器，这将使我们能够在电子显微镜中进行原位加热研究。这些研究对于我们在金属合金颗粒粗化和金属诱导脆化领域的研究计划是必不可少的。获得一个透射式电子显微镜对于大学内许多系的研究活动是必不可少的，这些系包括：机械和材料工程、物理、化学、地质、化学工程和电气工程。总共有15名研究生，他们的研究将直接受益于获得一台透射电子显微镜。此外，还有大约14名研究生参与了其他项目，他们的研究将显著受益于利用透射电子显微镜进行的微观结构研究。此外，校园内的电子显微镜将为研究生和本科生提供实质性的教学工具，使他们接触到目前他们无法获得的现代分析仪器。***

9311739 Norton This modern, research-grade 200kv transmission electron microscope with scanning and analytical capabilities for Washington State University will be used in an expanding, materials research and education program. Materials research has been identified as a high-priority area of emphasis at Washington State University. Two cross-college organizations-The Center for Materials Research and the Materials Science Program-have been recently established to address the interdisciplinary nature of Materials Science. The Center for Materials Research which consists of 19 senior participants was formed with the purpose of encouraging collaborative, cross-disciplinary research projects in the area of materials and applied condensed mater science. The Materials Science Program is the educational arm of the materials science thrust at Washington State University. The Materials Science Program was initiated in the Fall of 1990 and consequently is the most recently created Ph.D. program in the University. It is one of the few truly interdisciplinary programs in the nation as it involves active participation from both Engineering and Science departments. Twenty-two faculty members, from 6 departments participate in the Program. This instrument will permit conventional imaging in both bright-field and dark-field modes, high spatial resolution imaging, electron diffraction, and microanalysis of microstructural features in TEM specimens. A heating stage and temperature controller are also requested, which will enable us to perform in-situ heating studies in the electron microscope. These studies are essential for our research programs in the areas of particle coarsening of metallic alloys and metal induced embrittlement. Acquisition of a transmission electron microscope is essential for research activities in a number of departments within the University, including; Mechanical and Materials Engineering, Physics, Chemistry, Geology, Chemical Engineer ing, and Electrical Engineering. There are a total of 15 graduate students whose research will directly benefit from the acquisition of a transmission electron microscope. In addition, there are about 14 graduate students involved in the other projects whose research would significantly benefit from microstructural studies involving TEM. In addition a TEM on campus will provide substantial benefit as an instructional instrument for both graduate and undergraduate students, exposing them to modern analytical instrumentation which is not presently available to them. ***
