Abstract
The main target of this paper is the development of a forging die,made of hot working steel powder, equipped with internal cooling channels. For this purpose a copper rod is embedded inside the green body. Subsequently the copper has to be molten out. Therefore, the suitability of a pressure sintering process and a HIP-process is investigated. The design of the cooling channel is based on numerical simulations of thermal and mechanical stresses within the hot forging die. Furthermore, the study covers the influence of surface contours of the copper tubes (corrugated, plain) on their melting behavior as well as the resulting inner surface of the cooling channel.
