A method of obtain of sintered intermetallic alloys by pressing under cyclic loading at elevated temperature has been presented in this paper. Investigated samples were prepared as results of four different value of cyclic loading frequency of manufacturing process. Results of structure and phase analysis, especially in range of a content and morphology of aluminium oxides have been discussed. Basic mechanical properties of sinters estimated by microhardness measuring. On the basic of obtained results it has been shown that FeAl based intermetallic sinters may be treated as chemically and structurally heterogeneous materials with minimal content of pores.
