Sažetak
The article deals with mechanical properties of forgings used for special technology in cannon barrels production. The forgings are treated by elctroslag remelting technology (ESR) to enhance its plastic properties and yield point. Described experiments are focused on mechanical properties and metallurgical quality (microstructure) of steels from which are the forgings made. The article includes microstructure photographs and description of inclusions located in examined steels. Experimental results compare forgings treated by ESR and next ones without ESR.
