The structure of a multicomponent Ge55Al30Cr7Ni4Fe4 alloy prepared by arc-melting was examined using transmission electron microscopy (TEM) and energy dispersive x-ray analysis (EDS). The alloy structure was found to be inhomogeneous, consisting of nanosize crystalline particles of Ge24Al4Cr2NiFe metastable phase embedded in the amorphous matrix. The metastable phase had an Fm3m cubic lattice of a = 0.5635 nm. Crystallization of the amorphous phase led to formation of the Fd3m Ge and on unknown phase. The metastable phase disappeared through the reactions that take place over 700 K.
