Structure of Complex Concentrated Alloys Derived from Iron Aluminide FeAl.

The phase structure and composition of a series of four alloys based on FeAl was investigated by means of scanning electron microscopy, X-ray diffraction and transmission electron microscopy. The materials were composed of Fe and Al with a fixed ratio of 3:1 alloyed with V, Cr and Ni at 8, 12, 15 and 20 at. % each (composition formula: Fe AlVCrNi).
