Abstract: The use of embedded ceramic inserts in forging tools has lately been investigated and successfully tested with model forging dies. However, there is a danger of the mechanical widening of the steel tool as a major problem of forging dies with embedded ceramic inserts. Furthermore, only rotation symmetric ceramic inserts can be embedded, which allows only a small variety in the construction of tools. A considerably larger number of designs are possible for active metal brazing of ceramic inserts in the die|s body material. For achieving this, active brazed ceramic–metal compounds were developed and tested for their practical use in the forging process.

Keywords: active metal brazing; ceramic inserts; forging dies; wear reduction.
