This grant provides support for the acquisition of a nanoindenter for materials research and education at Carnegie-Mellon University. Installation of this instrument will benefit research and education programs in the Materials Science and Engineering department and across a broad range of activities in the engineering and science colleges. It will be the first such instrument at CMU. This new instrument offers the required capability of testing mechanical properties at the sub-micron scale. It will be a multi-user instrument that will be used for at least five major research projects, including one industrial partner.The major use of the instrument will be for research on dislocation structures from plastic deformation, cermet composites, thin films for microelectronic applications, probing of biological systems via mechanical properties, and oxide thin films for coatings. Anticipated results include a more fundamental understanding of the interaction between dislocations and grain boundaries; new insights into strain gradient plasticity; a more detailed understanding of mechanical property microstructure property relationships in cermets; an improved understanding of microstructural evolution in thin copper films for microelectronic applications; and information about the reaction of proteins to their environment. It is anticipated that researchers from other areas such as microelectromechanical systems and tissue engineering will request occasional use of the instrument.The scope of use of the instrument is broad and its acquisition will thus have broad impact on scientific activity in the materials area for Carnegie-Mellon University and its collaborators. Undergraduates will be trained in the use of a state-of-the-art instrument for probing mechanical properties through formal laboratory exercises. Current and future graduate students will have access to a much-needed tool to make advances in their research programs.

这笔赠款为卡内基梅隆大学购买用于材料研究和教育的纳米压痕仪提供支持。该仪器的安装将有利于材料科学与工程系的研究和教育项目以及工程和科学学院的广泛活动。这将是卡内基梅隆大学的第一个此类仪器。这种新仪器提供了亚微米级机械性能测试所需的能力。它将是一台多用户仪器，将用于至少五个主要研究项目，其中包括一个工业合作伙伴。该仪器的主要用途将是研究塑性变形产生的位错结构、金属陶瓷复合材料、微电子应用薄膜，通过机械性能探测生物系统，以及涂层的氧化物薄膜。预期的结果包括对位错和晶界之间相互作用的更基本的理解；对应变梯度可塑性的新见解；更详细地了解金属陶瓷的机械性能、微观结构性能关系；更好地了解微电子应用中铜薄膜的微观结构演变；以及有关蛋白质对其环境的反应的信息。预计微机电系统和组织工程等其他领域的研究人员偶尔会要求使用该仪器。该仪器的使用范围很广泛，因此它的获得将对卡内基材料领域的科学活动产生广泛的影响。梅隆大学及其合作者。本科生将接受培训，使用最先进的仪器通过正式的实验室练习来探测机械性能。当前和未来的研究生将能够获得急需的工具来推动他们的研究项目取得进展。
