The formation of the tetragonal Fe14La2B phase has been examined in both as-cast and melt-spun Fe-La-B alloys using thermal and magnetic techniques together with x-ray diffraction analysis. It is found that this phase exists in both types of alloys and that it is produced by annealing at relatively low temperatures. The Fe14La2B phase is unstable and is transformed to mostly α-Fe plus La-B upon annealing at higher temperatures.
