摘要：
Martensitic Fe-base alloys from the system Fe-Cr-C are widely used as chilled cast irons and tool steels. Because of the low hardness of their FeCr-carbides this paper reports about new alloys with primarily solidified harder niobium carbides. It focuses on a secondary hardenable welding alloy, a coating material for composite castings, a chilled casting and a corrosion resistant cold work tool steel, which are investigated with respect to their process related microstructure and abrasive wear behaviour.
