Inductive heating and semi-solid forming of high-melting materials

在第一个资助期内，斯图加特大学金属成形技术研究所(IFU)和机床与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过程。该研究项目的目标是将TiAl6V4加热到半固态，从而调整规定的固液比以及随后的近净成形过程。在第一阶段，证明了所开发方法的潜力。由于具有较高的科学价值和工业应用潜力，第二阶段的研究将扩大。因此，本文的研究工作集中在感应加热和半固态成形相结合的Ti6Al4V的工艺自动化以及加热控制和成形工艺参数的确定上。因此，关于加热过程的可靠性和半固态成形部件性能的重现性的测量方法的潜力有待于证明。此外，还必须研究和优化加热和成形工艺对材料S组织和由此产生的部件力学性能的影响。提交的工作包的目标是通过开发加热和成形的组合来证明技术生产工艺的适用性。

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.
