Peaks of XRD-patterns were interpreted as interferences of four phases: two solid solutions with FCC and BCC lattices and metastable intermediate phases with different lattice types. Thermodynamical stability of metastable phases during holding at room temperature was determined. It was established, that metastable intermediate phase with tetragonal lattice inherits short-range order parameters of clusters with tetragonal packing of atoms. On basis of experimental investigations it was shown that eutectic structure formed under influence of structure of the parent melt. The structure of melt can be changed in the issue of thermo-temporal treatment of it. This is corroborating certain abstract theorems of the theory of metallurgical heredity and concretizing these ones for eutectic silumin. Product Description popup.authors Бондарєв С.В. Зіборова Л.В.
