Abstract
Activation energies for crystallization of quasicrystalline Al4Mn and Al4(Cr0.5Fe0.5) Were determined from constant-heating-rate electrical resistivity measurements. Several consecutive metastable states, chara cterized by increasing activation energies, were noticed during this t ransformation. The Al4(Cr0.5Fe0.5) compound was found to be more stabl e against crystallization than Al4Mn.
