The preferential formation of Ni2Al3, Fe2Al5, and Ti2Al5 phases in aluminide systems
Original language description
The preferential formation of phases in Ni–Al, Fe–Al, and Ti–Al systems was observed at the interface of solidsolid and solid-liquid phases. It was found that phases already formed at temperatures lower than the melting point of aluminum. The Ni2Al3, Fe2Al5 and Ti2Al5 phases formed preferentially in the Ni–Al, Fe–Al and Ti–Al systems, respectively. The favored formation was not associated with thermodynamic assumptions, but was caused by crystal structures of arisen phases. The mentioned phases could form due to the two reasons, (i) similarities of their lattice parameters to lattice parameters of the individual elements (Ni, Fe, Ti, or Al) and (ii) the total volume of its lattice. The lattice volumes of Ni2Al3, Fe2Al5, and Ti2Al5 phases are always smaller than that of NiAl3, FeAl3, and TiAl3 phases. The last listed phases are ordinarily accepted by other authors as the phases, which form preferentially based on thermodynamic data only. This work disproves such claims and shows the reason for preferential phases’ formation.
