Abstract

The alloys based on intermetallic phases involving aluminum belong to group of heat resistant materials. Their physic-chemical and mechanical properties allow to apply them in the operating conditions in corrosive environment and elevated temperature. Research conducted for many years has shown that these materials can work in temperature to 1100 °C. The paper presents the morphology of oxides formed during oxidation Fe40Al5Cr0.2TiB alloy in 700 °C during 300, 1000 and 2000 h in the air and water vapor environment. In addition, the material was after casting and after plastic processing. The study allows to define the surface condition and morphology of corrosion products carried out using scanning electron microscopy together with EDS X-ray microanalysis.

Keywords: FeAl alloys, corrosion resistance, oxidation, Al2O3 scale
