Abstract
Recently the problem of the glass transition has been further complicated by the discovery of a phase which forms under conditions similar to those required by the formation of metallic glasses. This new phase (the “quasicrystal”) seems to be structurally intermediate between the glass and the crystal phase, being characterized by long-range orientational order and quasiperiodic translational order. The aim of this paper is to provide an introductory overview of this new field of quasicrystals. Experimental results and theoretical models are briefly presented.
