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.

该赠款为卡内基 - 梅隆大学的材料研究和教育纳米式材料研究提供了支持。该工具的安装将使材料科学和工程部门的研究和教育计划受益，并在工程和科学学院的各种活动中。它将是CMU的第一款这样的乐器。该新仪器提供了在亚微米尺度上测试机械性能所需的能力。这将是一种多用户仪器，将用于至少五个主要的研究项目，包括一个工业合作伙伴。该仪器的主要用途将用于研究塑性变形，CERMET复合材料，用于微电源应用的薄膜的脱位结构，通过机械性能探测生物系统的薄膜以及用于涂料的氧化物薄膜。预期的结果包括对位错和晶界之间的相互作用的更基本了解；对应变梯度可塑性的新见解；对Cermet中的机械属性微结构属性关系的更详细的理解；对微电子应用的薄铜膜中微结构进化的理解得到了进一步的了解；以及有关蛋白质对环境的反应的信息。可以预料，来自其他领域的研究人员，例如微机电系统和组织工程，将要求偶尔使用该仪器。该仪器的使用范围很广，因此其收购将对卡内基 - 梅隆大学材料领域的科学活动产生广泛的影响。本科生将通过正式的实验室练习来使用最先进的工具来探测机械性能的培训。当前和未来的研究生将可以使用急需的工具来进步其研究计划。
