项目摘要
Hot forming tools are locally influenced by high thermal, mechanical, chemical and tribological stresses, which usually occur at the same time. Particularly the thermal softening, which occurs during high temperature applications, often leads to premature failure of conventional forging tools due to plastic deformation in the engraving area.The overall objective of the proposed research project is to develop components out of a new metal matrix composite material (MMC) to increase the wear resistance of hot forming tools. Furthermore, the linkage between the MMC - component and the compact material is investigated. Therefor a pressure forming tool, which is constructively adapted to the present loads by using graded ceramic reinforcing phases, will be developed.The proposed forming tool will be composed out of several components. The main body will be made of conventional tool steel, while the highly stressed areas will be manufactured out of a newly developed MMC consisting of steel powder and ceramic hard material. The used MMC is specified by a layered structure of the ceramic reinforcing phase. A decreasing concentration of the ceramic reinforcing phase will simultaneous lead to strong mechanical properties at the engraving and good bonding qualities to the main body. To achieve a sufficient bonding quality between the compact material and the MMC - component, within this research, a number of joining operations will be developed and compared with one another. Finally, the operational behavior of the developed forging tools is examined in detail using a pressure forming process on an automated power press.
热成形工具局部受到高热、机械、化学和摩擦应力的影响,这些应力通常同时发生。特别是在高温应用过程中发生的热软化,往往会导致过早失效的传统锻造工具,由于在雕刻区域的塑性变形,拟议的研究项目的总体目标是开发出一种新的金属基复合材料(MMC)的组件,以增加热成形工具的耐磨性。此外,MMC组分和致密材料之间的联系进行了研究。因此,压力成形工具,这是建设性地适应目前的负载,通过使用梯度陶瓷增强相,将被开发。拟议的成形工具将由几个组成部分。主体将由传统的工具钢制成,而高应力区域将由新开发的由钢粉和陶瓷硬质材料组成的MMC制成。所使用的MMC由陶瓷增强相的层状结构指定。陶瓷增强相的浓度降低将同时导致雕刻时的强机械性能和与主体的良好结合质量。为了在致密材料和MMC部件之间实现足够的粘合质量,在本研究中,将开发许多连接操作并进行相互比较。最后,详细研究了所开发的锻造工具的操作行为,使用压力成形过程中的自动化动力压力机。
