Abstract
Abstract Hardness, microstructure and abrasive wear resistance of cast high-manganese steel (cast Hadfield steel) were compared with the cast steel of the same austenitic matrix but having vanadium carbides uniformly distributed within its entire volume. The chemical composition of the cast steel was chosen in such a way as to produce a composite structure after the alloy solidification. A similar hardness of the matrix was obtained with carbides evenly distributed in it, while abrasive wear resistance doubled its value. Using the investment casting process, working elements of teeth for the excavators and mechanical coal miners were cast.
