项目摘要
The project is aimed at developing and optimizing a new process for making titanium aluminide sheet materials that find application where structures are required to be fabricated using strong and light-weight materials that maintain their strengths at elevated temperatures. Intermetallic compounds such as TiAl are difficult process using conventional methods and require specialized/expensive techniques such as hot isostatic pressing with controlled inert atmospheres to minimize contamination. The goal of the project is to develop and optimize cold roll bonding process followed by reaction annealing of TiAl sheet samples. The study includes experimental investigation to determine the influence of surface preparation, rolling pressure, and annealing temperature on the microstructures and mechanical properties of the processed sheet. In addition to the tensile and hardness measurements, fracture toughness will be determined. Along with the experimental study, simulation of the cold roll bonding process will made using numerical modeling so that the effects of deformation on the rate of reaction during annealing can be assessed. The fundamental metallurgical investigations will lead to a better understanding of the factors controlling the microstructures and properties of materials processed by cold roll bonding. The funding of this research provides an opportunity for graduate and undergraduate students including underrepresented minorities to develop understanding and experience in the metallurgical and process areas of research.%%%This research develops a new processing method to fabricate intermetallic metals and alloys that find application in several technologies with high temperature applications including aerospace. It is anticipated that this process on a commercial scale can produce relatively large intermetallic sheets measuring several meters. These materials preserve their mechanical strength at relatively high temperatures. The proposed processing eliminates expensive hot isostatic pressing in inert atmospheres making it relatively more cost-effective.
该项目旨在开发和优化一种制造钛铝化物板材的新工艺,该工艺适用于需要使用坚固而轻质的材料来制造结构的地方,这些材料在高温下保持其强度。TiAl等金属间化合物使用传统方法很难加工,需要专门的/昂贵的技术,如在受控惰性气氛下进行热等静压,以将污染降至最低。该项目的目标是开发和优化冷轧连接工艺,然后对TiAl薄板样品进行反应退火。该研究包括实验研究,以确定表面准备、轧制压力和退火温度对加工板材的组织和力学性能的影响。除了拉伸和硬度测量外,还将测定断裂韧性。在进行实验研究的同时,还将利用数值模拟的方法对冷轧结合过程进行模拟,以评估变形对反应速率在退火期的影响。基础的冶金研究将有助于更好地理解控制冷轧连接材料的组织和性能的因素。这项研究的资助为研究生和本科生提供了一个机会,让他们在冶金和工艺研究领域发展了解和经验。%这项研究开发了一种新的加工方法来制造金属间化合物和合金,这些金属和合金在包括航空航天在内的多种高温应用技术中得到了应用。预计商业规模的这一工艺可以生产较大的金属间化合物薄板,尺寸为几米。这些材料在相对较高的温度下保持其机械强度。建议的工艺消除了在惰性气氛中昂贵的热等静压,使其相对更具成本效益。
