Mukherjee DMI-9615540 Laminated Metal Composite (LMC) provides a very high strength and exceptional fracture toughness for the transportatimn industry, in particular, for aerospace and high speed grould vehicle applications. To realize its full potential applications, technical advances in near-net shape manufacturing is required. The current state of knowledge regarding LMC is lacking in understanding of the microstructure and process characteristics of the formed LMC. This research project investigates the process characteristics and the superplastic formability of multilayered laminated metal composites (LMC) which consists of aluminum-based metal alloy and metal-matrix monolithic layered materials. The specific goal of this project is to understand the microstructure of the LMCs and to provide better control parameters in the manufacturing process. The outcomes of this study could provide useful findings for die designs and a better furnace capabilities to carry out the effective forming operation. This collaborative research project addresses fundamental issues on the characterization of microstructure of the near-net shape LMC manufacturing process. The research project has a balance between theory and experiment, and will provide valuable findings for the laminated metal composite industry.

慕克吉 粤ICP备15015540号-1 层压金属复合材料（LMC）为运输工业，特别是航空航天和高速地面车辆应用提供了非常高的强度和优异的断裂韧性。 为了实现其全部潜在的应用，需要在近净成形制造方面取得技术进步。 关于LMC的知识的当前状态缺乏对所形成的LMC的微观结构和工艺特性的理解。 本研究主要探讨铝基金属合金与金属基整体层状材料所组成的多层层状金属复合材料（LMC）的工艺特性与超塑性成形性。 该项目的具体目标是了解LMC的微观结构，并在制造过程中提供更好的控制参数。 本研究结果可提供模具设计及改善炉体性能以进行有效成形作业之参考。 该合作研究项目解决了近净形LMC制造工艺微观结构表征的基本问题。 本研究项目在理论和实验之间取得了平衡，将为层压金属复合材料工业提供有价值的研究成果。
