Intermetallic phases, as a group of materials which have a great practical importance, both in the past and in the present day, are subject of research on the basis of physicochemical and mechanical properties. The presented studies were conducted for Fe40Al5Cr0.2TiB intermetallic alloy, their purpose was to determine the corrosion resistance of this alloy in an oxidizing environment, at temperatures up to 1373 K. The test material was made of Fe40Al5Cr0.2TiB intermetallic alloy after plastic processing. The kinetics of corrosion, allotropic variants according to the temperature of the process and the surface condition after corrosion were determined during the study. Based on the results obtained, the verification was performed under operating conditions. Taking into account the properties of the FeAl alloys, the working conditions and material requirements of turbochargers, studies have been undertaken to determine the possibility of the use of Fe40Al5Cr0.2TiB intermetallic alloys for components of the hot turbocharger of the automobile with compression ignition engines. The components of the hot turbocharger parts were used from the test material. The tests distance of turbocharger was 80,000 km.
