The increasing demand for improved metallurgical products strongly motivates the optimization of manufacturing processes and design of γ-TiAl products. Among the large variety of available forming processes, cold closed-die forging is particularly suitable for producing net shape bulk products having good surface finish with better mechanical properties. Pressing punches of suitable profile are required to plastically form the material into desired geometries. Computer modeling represents an effective and cost effective method to find optimal process setup conditions together with optimal product geometry and material properties. The present work focuses on the feasibility study of uniaxial cold closed-die forging of shaped and flat γ-TiAl thick disks by computer modeling.
