Extrusion die design and production from Inconel 718 superalloy material

Abstract

In this study, extrusion mold design and manufacturing were examined using Inconel 718 superalloy material to address critical issues in the production process. The aim was to prevent production disruptions caused by thermal fatigue, hot tearing, thermal shock, abrasion, and other mechanical deformations. The use of a material with advanced mechanical properties was targeted for this purpose. Inconel 718 and hot work tool steel were compared, evaluating chemical composition, surface roughness, and conductivity. It was concluded that Inconel 718, with its higher Cr content, superior mechanical properties, and similar conductivity values, provides advantages in the production process.
