Transformation processes during annealing of Al-amorphous alloys

As the amorphous aluminum alloys represent the newest achievement in rapid solidification of Al-based high strength heat resistant materials, a study was undertaken on the amorphous alloys in the Al-RE-TM system, the rare-earth metal being a lanthanide mixture and the transition metal a Ni-Fe substitution in definite proportions. The decomposition on heating of the most highly alloyed amorphous alloy in the investigated series is characterized by differential thermal analysis, electron microscopy and X-ray diffraction
