Notes:
This paper deals with the examination of the steel grade X210CrW12 and its suitabilityfor Thixoforming. In the semi-solid state, the microstructure of this steel consists of a homogeneousdistribution of globular particles surrounded by liquid. Additionally, carbides are stabile up tofraction liquid contents of approximately 40%. After quenching, this steel reveals a globularaustenitic microstructure with eutectic (former liquid phase) at the grain boundaries. Compressiontests permit to determine the influence of different process parameters on the properties and thematerial behaviour in the semi-solid state. Their influence on the microstructure was investigatedbut not yet highlighted. Further investigations on this steel allow a fine-tuning to establish optimalprocess windows of the different thixoforming- and rheoforming- routes
