Abstract
Calorimetric and electron diffraction studies reveal that the quasicrystalline-to-crystalline phase transition in Al6CuMg4 is endothermic, in contrast to the exothermic crystallization in quasicrystalline Al-Mn reported earlier. This finding indicates that the stability of certain quasicrystalline phases may be much larger than that of the Al-Mn system. This finding is in agreement with the prediction based on quantum structural diagrams. From a kinetic study the activation energy of this phase transition was found to be 260 kJ/mole.
