The book series Ternary Alloys provides intellectual critical evaluation of all published data and facts on each individual materials system. Each evaluation report is a concise and - as far as published data allow – consistent phase diagram description for an individual binary or ternary system. The world literature is thoroughly and systematically searched back to the year 1830. Then, the published data are critically evaluated by the MSIT experts in materials science and peer-reviewed under the authority of the MSIT Editorial Board.
