In 1994 we will mark the tenth anniversary of the discovery of quasicrystals, aperiodic crystals which lie outside the framework of traditional crystallography and which have disturbed the theory and practice of solid state physics, bringing in new perspectives. Already a substantial international community working on this topic has developed, with its own social structure, and it is time to assess the progress of the past decade and to consider future possibilities.
1994 marks the tenth anniversary of the discovery of quasicrystals, aperiodic crystals which lie outside the framework of traditional crystallography and which have disturbed the theory and practice of solid state physics, bringing in new perspectives. A substantial international community, with its own social structure, works on this topic. It is time to assess the progress of the past decade and to consider future possibilities. Drawn from the International Symposium on Quasicrystals and Imperfectly Ordered Crystals held in Chengde, China, August/September 1993, this volume presents 49 papers covering most of the important topics relevant to further development in this field. Some of the highlights include: "The generalization of orthodox crystallography" by A.L. Mackay; "The structure of quasicrystals" by W. Steurer; "Physical properties of quasicrystals - an experimental review" by S. Takeuchi; "Modulated quasicrystals" by T. Janssen; "A HREM study of the 1/1,2/1 and 2/1,1/1 orthorhombic approximants in an A1CoNiTb alloy" by K.H. Kuo et al; "Structural relationships between crystalline approximant phases and decagonal Mn-A1 phase" by C.B. Shoemaker.
