项目摘要
This proposal is to develop and demonstrate a system for in- process characterization of a signature representing the properties and thus the stamping and forming characteristics of copper alloy strip. The development will be accomplished by combined application of three techniques (acoustic, eddy current, and X-ray diffraction) for non-intrusive characterization of polycrystalline metal alloys. These non-contact techniques were specifically selected for their complimentary nature and real time capabilities. Selection was the result of a prior NSF grant. Each of the techniques selected for the combined measurements is sensitive to different sets of characteristics and thus will provide a sensitive system for measuring interdependent changes in these characteristics. The three techniques will accomplish interrogation of different volumes of the subject material due to the various depth of probing offered by the teamed system. An experimental approach will be employed to develop and demonstrate the system. Relations will be developed relating the teamed signature to the mechanical properties and stamping and forming characteristics of the copper alloy strip. Electronic copper alloy strip was selected as the class of materials and the fabrication of switches and contacts as the forming process on which to focus. The methodology developed by this work for combining various measurements should have generic value and permit application to other materials and processes. The combined application of the three measurement techniques is novel. This research should lead to in-process measurement of properties and fabrication characteristics of wrought metallic alloys which should result in significant improvement in productivity and quality.
本提案是开发和演示一个系统,用于表征表征铜合金带材的性能,从而表征冲压和成形特性的签名。该开发将通过三种技术(声学、涡流和x射线衍射)的联合应用来完成多晶金属合金的非侵入性表征。这些非接触式技术因其优点和实时功能而被特别选择。选择是先前NSF资助的结果。为组合测量所选择的每一种技术对不同的特征集都很敏感,因此将为测量这些特征的相互依赖变化提供一个敏感的系统。由于团队系统提供的探测深度不同,这三种技术将完成对不同体积的主题材料的讯问。将采用实验方法来开发和演示该系统。研究了组形特征与铜合金带材的力学性能、冲压成形特性之间的关系。以电子铜合金带材为材料类别,以开关和触点的制造为成形工艺重点研究。由这项工作开发的用于组合各种测量的方法应该具有通用价值,并允许应用于其他材料和过程。三种测量技术的结合应用是新颖的。这项研究将导致在加工过程中测量变形金属合金的性能和制造特性,从而显著提高生产率和质量。
