The cast alloys crystallizing in Fe-C-V system are classified as white cast iron, because all the carbon is bound in vanadium carbides. High

vanadium cast iron has a very high abrasion resistance due to hard VC vanadium carbides. However, as opposed to ordinary white cast

iron, this material can be treated using conventional machining tools. This article contains the results of the group of Fe-C-V alloys of

various microstructure which are been tested metallographic, mechanical using an INSTRON machine and machinability with the method

of drilling. The study shows that controlling the proper chemical composition can influence on the type and shape of the crystallized

matrix and vanadium carbides. This makes it possible to obtain a high-vanadium cast iron with very high wear resistance while

maintaining a good workability.
