The Thixoforming of metals is a new forming technology, which combines the advantagesof casting and forging. This technology focuses on structural components with complex shapes,which can not be manufactured using conventional processing methods. Different components madeof aluminum and magnesium are already industrially produced. Apart from this, the use of steels inthe Thixoforming processes is still being researched and developed. During the last years it becameobvious that the Thixoforming of steels may not be a complete substitution for highly automateddie-casting or forging processes, but rather a new process route to produce special components withhigh quality and geometrical demands. Special interest lies in the development and production offiligree components, parts with voids or undercuts, integrated elements such as tubes or tube-systemsand joining pieces or products made of different materials. Beside the design of suitable toolmaterials and tool concepts, the development of homogeneous heating strategies and thedevelopment of thixoformable steels is at the center of current research. Therefore, this paper focuseson material requirements which are needed for the Thixoforming of steels and on the production ofcomponents and occurring problems. By use of a failure catalogue for Thixoforming of steels,reasons for characteristic failures and suggestions are given to avoid them, so that the quality ofthixoformed parts can be improved
