*** 96-61025 Mroz This Phase I Small Business Innovation Research project will investigate a new family of ternary carbide compounds which have initially shown an interesting combination of ceramic and metallic characteristics. These materials exhibit a set of characteristics that blends the ductility, shock resistance and machinability of metals with the refractoriness, oxidation resistance and strength of ceramics. These new compositions have been initially evaluated, however they have not been reproduced elsewhere. In order to learn more about these materials, and at the same time, further evaluate structure/properties relationships, a research program based on compositional variations is suggested. The project will evaluate the specific lattice sites within the structure as they relate to the material characteristics by exchanging specific elements with related elements. This will provide changes in atomic size and or valence potential. The formation of extensive solid solutions in this composition range, which will allow for determination of characteristics as they relate to changes made in atomic composition is anticipated. These materials will be characterized and compared to earlier work from the original researchers responsible for discovering these materials. In addition, the project will begin to evaluate and prioritize commercial opportunities for this material as they relate to the properties and characteristics obtained from sample materials. Applications for this family of materials are expected to be wide ranging. Early analysis suggests that replacement for graphite parts will be a large market that can be satisfied by the improved electrical and wear performance of these materials. Other applications might include electrodes, heaters, seals and wear parts, and engine components. The total value of the markets that may be serviced by this material is quite large due to the pervasive nature of the technology. ***

*** 96-61025 Mroz 该第一阶段小型企业创新研究项目将研究一个新的三元碳化物化合物系列，该化合物最初显示出陶瓷和金属特性的有趣组合。这些材料表现出一系列特性，将金属的延展性、抗冲击性和可加工性与陶瓷的耐火性、抗氧化性和强度融为一体。这些新作品已经过初步评估，但尚未在其他地方复制。为了更多地了解这些材料，同时进一步评估结构/性能关系，建议采用基于成分变化的研究计划。该项目将通过交换特定元素与相关元素来评估结构内与材料特性相关的特定晶格位置。这将提供原子尺寸和/或价势的变化。预计在此成分范围内形成广泛的固溶体，这将允许确定与原子成分变化相关的特性。这些材料将被表征，并与负责发现这些材料的原始研究人员的早期工作进行比较。此外，该项目将开始评估这种材料的商业机会并确定其优先顺序，因为它们与从样品材料获得的性能和特性有关。 该系列材料的应用预计将非常广泛。 早期分析表明，石墨零件的替代品将是一个巨大的市场，可以通过这些材料改进的电气和耐磨性能来满足。 其他应用可能包括电极、加热器、密封件和磨损部件以及发动机部件。 由于该技术的普遍性，这种材料可能服务的市场总价值相当大。 ***
