This research program is directed towards a new innovation, Friction Stir Channeling (FSC). FSC produces a continuous hole in a monolithic plate. The objectives of this program are: (a) process development to produce an integral channel (also referred as conformal channel), (b) microstructure-property correlation of material around the channel, and (c) influence of channel shape, size and surface characteristics on performance of the heat exchanger. General Tool Company and NASA-Johnson Space Center are partners in this program. The process is capable of producing non-linear channels on a complex component with robotic friction stir welding machine. FSC offers several new opportunities as 'technology enabler.' Some examples are: integral channel(s) in a plate, cooling channels in tubular parts for semiconductor processing equipment, and conformal cooling channels. This program is likely to have several broader impacts. On the educational front, it will bring innovative ideas to undergraduate courses such as metal deformation processing and metals structure-property laboratories. Undergraduate researchers will be involved through the UMR-OURE program and the support from the Center for Friction Stir Processing at UMR. Heat exchangers are commonly used to alter the temperature of an operating system or heat transfer and total market is several billions of dollars. Friction stir channeling has the potential to create impact in several sub-components of this market, specifically, die casting and permanent mold industries, cold plate heat exchangers and semiconductor processing equipments. General Tool Company is one of the leading manufacturers of friction stir welding and processing machines and their involvement will result in technology transfer and successful implementation.

本研究项目针对的是一种新的创新--搅拌摩擦导流法。FSC在整体板上产生一个连续的孔。该计划的目标是：(A)工艺开发以生产完整的通道(也称为保形通道)，(B)通道周围材料的微观结构-性能关联，以及(C)通道形状、尺寸和表面特性对换热器性能的影响。通用工具公司和NASA-约翰逊航天中心是该计划的合作伙伴。该工艺能够在机器人搅拌摩擦焊机上对复杂零件进行非线性通道的加工。金管会提供了几个新的“技术推动者”的机会。例如：平板中的整体通道(S)，半导体加工设备管状零件中的冷却通道，以及保形冷却通道。这一计划可能会产生几个更广泛的影响。在教育方面，它将为本科生课程带来创新思想，如金属变形加工和金属结构-性能实验室。本科生研究人员将通过UMR-OURE项目和UMR搅拌摩擦加工中心的支持参与进来。热交换器通常用于改变操作系统或热传递的温度，总市场价值数十亿美元。摩擦搅拌沟槽有可能在这个市场的几个子领域产生影响，特别是压铸和金属模具行业、冷板热交换器和半导体加工设备。通用工具公司是搅拌摩擦焊接和加工设备的领先制造商之一，他们的参与将导致技术转让和成功实施。
