Abstract
In forging, premature die failure caused by high cyclic thermo-mechanical loads leads to higher production costs. The die life can be increased by using high strength materials like nickel-based alloys (Inconel). However, the application of Inconel as die material is challenging due to its high costs and poor machinability compared to conventional tool steels. Therefore, an approach to produce hybrid dies consisting of hot working tool steels and Inconel according to the Tailored Forming concept is presented. The dies are manufactured by forging pre-joined semi-finished workpieces. To resolve challenges like different flow behaviours, first a material characterisation of two hot working tool steels (1.2343/1.2367) and two Inconel alloys (625/718) was carried out using uniaxial compression tests. Based on the determined mechanical properties suitable process windows were investigated and FE-simulations for the hot forming of hybrid Inconel and tool steel semi-finished workpieces were carried out to investigate the resulting material distribution.
