Acquisition of Equipment to Assist in the Synthesis and Property Measurement of Bulk Amorphous and Nanocrystalline Metal Alloys

用于合成和表征大块非晶和纳米晶金属合金的Shiflet设备将被弗吉尼亚大学收购。该仪器包括一个用于金属合金熔炼纺丝和感应熔炼的振荡器电源，一个用于高温机械测试的熔炉，一个显微硬度测试仪，扫描力显微镜的升级和附件，以及用于制造群集组装材料的机器的部件。将使用所要求的设备的研究活动包括金属玻璃和纳米晶体材料的合成和特性，研究尺寸和形状对小型沉淀结合的影响，以及金属玻璃合金的形态和腐蚀。这项研究填补了国家对新型大块金属玻璃和纳米晶体材料重要领域的研究和教育活动的需求。这些新材料的性能具有足够的潜力，因此国外已对其进行了大量的投资研究。重要的是，在美国也要保持强有力的努力。＊＊＊

9601651 Shiflet Equipment for the synthesis and characterization of bulk amorphous and nanocrystalline metal alloys will be acquired by the University of Virginia. The instrumentation includes an oscillator power supply for use in melt-spinning and induction melting for metal alloys, a furnace for mechanical testing at high temperatures, a microhardness tester, upgrades and attachments to a scanning force microscope, and parts for building a machine for making cluster-assembled materials. Research activities that will use the requested equipment encompass the synthesis and characterization of metallic glasses and nanocrystalline materials, studies of size and shape effects on the coalescence of small-scale precipitates, and morphology and corrosion of metallic glass alloys. %%% The research fills a national need for both research and educational activities in the important area of new bulk metallic glasses and nanocrystalline materials. The properties of these new materials have sufficient potential that a considerable investment has been made abroad for their study. It is important that a strong effort be maintained in the US as well. ***
