Forming in the thixotropic state is one of the alternative forming methods, which allows producing semi-products with relatively complicated shape. The process is based on semi-product forming in the region between solid and liquid, where the material exhibits the thixotropic behaviour. Among the advantages of this technology belongs the possibility to produce components with complicated shape in one step and to utilize lower forming forces. On the other hand, high forming temperatures and the narrow forming temperature interval can be considered as disadvantages. A die was designed for this technology and practical testing was carried out using a range of forming strengths and temperatures. The shape of the hollow was varied to find out fluidity. Steel workpieces of various shapes several millimetres in size were created using this technology. The tool steel X210Cr12 was used for the development of an alternative forming process. The structures were observed using light and laser confocal microscopy.
