0932724GraedelFor the most part, the long term availability of "specialty metals" of great importance to society (e.g., hafnium, niobium, molybdenum, cobalt, tantalum, etc.) is essentially unknown. Methodology for assessing the "criticality" of these materials will be used together with extensive data on geology, product engineering, and other relevant factors to evaluate the criticality of twelve metals central to modern technology. This will provide a comprehensive analytical framework for assessing the criticality of the specialty metals, as well as new guidance to product designers and industry and government managers and policy makers. The results of this research are anticipated to be immediately employable critical materials information for sectors including corporate design engineers, international trade analysts, industry institutes, and the National Defense Stockpile Center. Additionally, the research project will train a dozen young scientists and engineers in the assessment of the long-term sustainability of materials.

大多数情况下，对社会非常重要的“特殊金属”的长期可获得性(例如，Hf_n、Nb、Mo、Co、Ta等)基本上是未知的。评估这些材料的“关键程度”的方法将与地质、产品工程和其他相关因素的大量数据一起使用，以评估对现代技术至关重要的12种金属的关键程度。这将为评估特种金属的关键程度提供一个全面的分析框架，并为产品设计师、行业和政府管理人员以及政策制定者提供新的指导。这项研究的结果预计将立即成为企业设计工程师、国际贸易分析师、工业研究所和国防储备中心等部门的关键材料信息。此外，该研究项目还将培训十几名年轻的科学家和工程师，以评估材料的长期可持续性。
