Description: This is a scientific article, which reviews the stability of various icosahedral quasicrystals (iQc) from a metallurgical viewpoint. The stability of stable iQcs is well interpreted in terms of Hume-Rothery rules, i.e. atomic size factor and valence electron concentration, e/a. For metastable iQcs, the role of phason disorder introduced by rapid solidification, in structural stability and its interplay with chemical order and composition is discussed. The article is publshed in Sci. Technol. Adv. Mater. 9 (2008) 013008 (20pp); DOI:10.1088/1468-6996/9/1/013008.
