项目摘要

The research objective of this award is to determine how the dry sliding wear behavior and wear mechanisms of a range of recently-discovered, very high strength, nanostructured FeNiMnAl spinodal alloys vary with changes in microstructure such as phase size and composition. Testing will be performed at a range of speeds in air, argon and oxygen in order to understand the effects of local heating and of oxidation, including the role played by wear debris. The project will utilize a range of state-of-the-art techniques to characterize the pre- and post- wear specimens including transmission electron microscopy (TEM) coupled with X-ray spectroscopy; profilometry; X-ray diffraction; nanoindentation; cross-sectional scanning electron microscopy, and atom probe tomography (APT). The observed wear behavior will be modeled. The work will involve several collaborations: alloys will be drop cast at the Oak Ridge National Laboratory (ORNL) by Dr. Easo George; high temperature wear experiments will be carried out at the ORNL Tribology Research User Center in collaboration with Dr. Peter J. Blau; APT will be performed at ORNL with the aid of Dr. Mike K. Miller; and focused ion beam cross-sectioning/TEM will be performed with the aid of Professor Paul Munroe of the University of New South Wales, Australia.If successful, the project will not only provide an understanding of the relationship between the microstructure, deformation processes and the wear behavior of FeNiMnAl spinodal alloys, leading to their possible commercial utilization, but will contribute to understanding the wear behavior of spinodal alloys as a class of materials, which have been little studied. It will also lead to the development of cutting edge techniques to study wear. The project will train both a Ph.D. student and several undergraduates. The results will be published in refereed journals and presented at various conferences.
该奖项的研究目标是确定最近发现的一系列非常高强度的纳米结构FeNiMnAl spinodal合金的干滑动磨损行为和磨损机制如何随微观结构(如相尺寸和成分)的变化而变化。测试将在空气、氩气和氧气中以一定的速度进行,以了解局部加热和氧化的影响,包括磨损碎片所起的作用。该项目将利用一系列最先进的技术来表征磨损前后的样品,包括透射电子显微镜(TEM)和x射线光谱学;轮廓测定法;x射线衍射;nanoindentation;横断扫描电子显微镜和原子探针断层扫描(APT)。将对观察到的磨损行为进行建模。这项工作将涉及几项合作:合金将由Easo George博士在橡树岭国家实验室(ORNL)滴铸;高温磨损实验将在ORNL摩擦学研究用户中心与Peter J. Blau博士合作进行;APT将在ORNL进行,由Mike K. Miller博士协助;聚焦离子束横切/透射电镜将在澳大利亚新南威尔士大学Paul Munroe教授的协助下进行。如果成功,该项目不仅将提供对FeNiMnAl spinodal合金的微观结构、变形过程和磨损行为之间关系的理解,从而导致其可能的商业应用,而且将有助于理解spinodal合金作为一类材料的磨损行为,这类材料的研究很少。这也将导致研究磨损的尖端技术的发展。该项目将培养一名博士生和几名本科生。研究结果将发表在评审期刊上,并在各种会议上发表。
