CHARACTERIZATIONS AND ELECTRON PARAMAGNETIC RESONANCE (EPR) QUASICRYSTALS IN AN ICOSAHEDRAL PHASE

ABSTRACT This article deals with a study on the icosahedral phase quasicrystal of Al63Cu25Fe12 produced by casting in plasma induction furnace under an argon atmosphere to guarantee it's homogenously. But found in phase transformations from one phase to another, the structures formed by the qua...
