For everyone concerned with the technology and application of metals and alloys and with the development of new metallic materials a detailed knowledge of phase equilibria is indispensable. Also, information on the thermodynamical and crystallographical data of the systems under investigation is essential, and often metastable crystalline phases as well as quasicrystalline or amorphous alloys are of interest.

The first volume of this series has been published in 1991. Since then a remarkable progress in the investigation of binary alloys has been achieved, which necessitates a compilation of the new data in supplement volumes. The present subvolume IV/12 forms the supplement to the subvolume IV/5A. It covers the literature up to the year 2000.
