| Description
| - Mechanical properties of metallic materials depend on their chemical composition and on microstructure, which can be altered by various heat treatment or thermomechanical treatment processes. Semi-solid processing is one of unconventional methods, which can be used for altering the microstructure and as well as for the manufacturing components with intricate shapes. The purpose of this experimental pro- gramme was to investigate the influence of transition of the X210Cr12 steel through semi-solid state on their hot deformation behaviour. The typical microstructure of this steel after semi-solid processing con- sisted of more than 95% of austenite located in quasi-globular austenitic grains and the austenite-carbide eutectics placed in the area among the austenitic grains. During experimental regimes, the specimens were heated into the semi-solid state. Immediately after the transition through semi-solid state, the material was cooled down to hot forming temperature, deformed and then cooled down in a controlled manner. The deformation was performed in three steps in the temperature interval from 1100 ? C to 870 ? C and the cooling rate after deformation from 1.2 K/s to 500 K/s. Reducing the deformation temperature led to the considerable grain refinement. The hardness of the microstructure was influenced by temperature interval of deformation as well as by the cooling rate reaching the values from 370 to 465 HV10.
