The process of cavitational erosion induces destruction of a material which consists of plastic strains, mass decrements, phase changes, grain fragmentation and surface micro- and macro-geometry changes. Heterogeneity of this process causes the destruction of a solid body due to cavitation to be hard to predict. Examinations of many materials showed that the course of cavitation wear is basically affected by structure which allows for orientation and size of grains and their shape, fraction of small and large angle boundaries, type of phases (in multi-phase materials), interposition of their grains, grain volume fraction as well as distribution of impurities and possible defects of materials, such as cracks, pores and non-metallic inclusions. The aim of this study was to examine the effect of structure on the cavitational wear of FeAl intermetallic phase-based alloys with cubic lattice.
