项目摘要

During the first funding period, the Institute for Metal Forming Technology (IFU) and the Institute for Control Engineering of Machine Tools and Manufacturing Units (ISW) of the University of Stuttgart investigated the inductive heating and the semi-solid forming process of high-melting material systems. Objective target of the research project is the heating of TiAl6V4 up to the semi-solid state and, thereby, the adjustment of defined ratios of solid and liquid phases as well as the following near-net-shape forming process. In the first period, the potential of the developed method was proved.By reason of the high scientific value and the potential for industrial applications, the investigations are to be expanded in the second period. Thereby, the research work is focusing on the combination of inductive heating and semi-solid forming of Ti6Al4V with regard to the process automation as well as the determination of parameters for heating control and forming process. Thus, the potential of the measuring method regarding the reliability of heating process and the reproducibility of properties of the semi-solid formed components is to be demonstrated. Furthermore effects of the heating and the forming process on material´s microstructure and on resulting mechanical properties of the components have to be investigated and optimized. The objective target of the submitted work packages is to demonstrate the applicability of the technical production processes by developing a combination of heating and forming.

在第一个资助期内，斯图加特大学金属成形技术研究所（IFU）和机床和制造单元控制工程研究所（ISW）研究了高熔点材料系统的感应加热和半固态成形工艺。该研究项目的目标是将TiAl6V4加热到半固态，从而调整固液相的规定比例以及随后的近净成形过程。在第一阶段，已证明了所开发方法的潜力。由于其高科学价值和工业应用潜力，将在第二阶段扩大研究。因此，本论文的研究工作主要集中在感应加热与Ti6Al4V半固态成形相结合的工艺自动化、加热控制参数和成形工艺参数的确定等方面。因此，关于加热过程的可靠性和半固态成形部件的性能的再现性的测量方法的潜力将被证明。此外，加热和成型工艺对材料微观结构和部件机械性能的影响必须进行研究和优化。提交的工作包的目标是通过开发加热和成型的组合来证明技术生产工艺的适用性。
