This Grant Opportunity for Academic Liaison with Industry (GOALI) award supports research leading to new knowledge related to the manufacturing of metals, that will advance the science base of manufacturing and provide competitive technological benefits for the national economy. The process is directed at the formation of specialty metal sheet and foil that is needed in applications within the aerospace, energy systems, ground transportation and biomedical sectors. Currently, the majority of metal sheet is produced by rolling processes which, despite having attractive benefits, also have important limitations pertaining to control of properties, cost, infrastructure and energy. The shear-based deformation processing approach utilizes variants of machining-based processes to create metal sheet and foil in a single step from bulk ingot, while employing a compact manufacturing systems infrastructure. The metal sheet will have superior mechanical properties, because of unique process capability to control deformation parameters. Furthermore, the machining-based processing offers important economic benefits compared to current sheet-production technology in terms of cost and energy usage. The process will be particularly suited for production of sheet from specialty alloys like titanium, magnesium and aluminum, which are of interest for high-performance and/or lightweighting applications in critical industry and defense sectors. This interdisciplinary research requires participation of manufacturing, materials engineering and systems science. The multi-disciplinary approach will also contribute to broadening the participation of underrepresented groups in research, and positively impact engineering education.To establish the capability of the machining-based processing for commercial sheet production, the university-industry team is addressing three closely related technical objectives using titanium alloys as a model material system. Firstly, process deformation fields will be analyzed using in situ high-speed imaging, complemented by force/energy analysis. Secondly, sheet metal properties will be characterized through quantitative microstructure and crystallographic texture analyses; and strength and formability measurements. New shear-based textures, combined with fine-grained microstructures, are of particular interest. Correlations will be established between deformation fields, microstructure and properties in the form of a process map. Thirdly, building on the process mapping, process scaling and systems analysis (quality, cost, energy, equipment design) will be used to produce sheet with enhanced mechanical properties and commercial quality. The envisaged outcome is new process capability for producing commercial titanium alloy sheet at less than 1/10 the cost of current state-of-the-art processing, with future extension to other advanced material systems.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项与行业联络的赠款机会（Goali）奖支持了与金属制造有关的新知识的研究，这将推动制造业的科学基础，并为国民经济提供竞争性的技术利益。该过程针对航空航天，能源系统，地面运输和生物医学领域的应用所需的特种金属板和箔的形成。目前，大多数金属板是由滚动过程产生的，尽管滚动过程具有吸引人的好处，但也具有与控制财产，成本，基础设施和能源有关的重要局限性。基于剪切的变形处理方法利用基于加工的过程的变体来从散装铸币厂进行单一步骤创建金属板和箔纸，同时采用紧凑的制造系统基础架构。金属板将具有卓越的机械性能，因为它具有独特的控制变形参数的能力。此外，与当前生产技术相比，基于加工的处理在成本和能源使用方面提供了重要的经济利益。该过程将特别适合从钛，镁和铝等特种合金生产纸，这对于在关键行业和国防部的高性能和/或轻量级应用感兴趣。这项跨学科研究需要制造，材料工程和系统科学的参与。多学科方法还将有助于扩大代表性不足的小组参与研究的参与，并对工程教育产生积极影响。为了确定基于加工的商业工作表生产的能力，该大学行业团队正在解决三个使用钛合金作为模型材料系统的三个密切相关的技术目标。首先，将使用原位高速成像分析过程变形场，并通过力量/能量分析互补。其次，将通过定量的微结构和晶体纹理分析来表征金属钣金性能。以及强度和可表达性测量。新的基于剪切的纹理，再加上细粒的微观结构，特别感兴趣。将以过程图的形式建立变形字段，微结构和属性之间的相关性。第三，基于过程映射，过程规模和系统分析（质量，成本，能源，设备设计）的构建将用于生产具有增强机械性能和商业质量的纸。设想的结果是新的流程能力，可用于生产商业钛合金表，小于1/10，即当前的省略处理处理成本，将来扩展到其他先进的材料系统。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估来通过评估来获得支持的。
