Literature Data

This ternary system contains many technologically important alloys, present and future applications. Accordingly, the phase equilibria of the system have been reviewed [1934Fus, 1943Mon, 1952Han, 1961Phi, 1969Gue, 1973Wil, 1976Mon, 1979Cha] from time to time. Köster [1941Koe3] was the first to report the entire liquidus surface and it was subsequently modified by [1960Arn2]. Isothermal sections in the temperature range of 200 to 700°C have been determined by several researchers [1932Bau1, 1932Bau2, 1932Bau3, 1940Geb, 1941Geb1, 1941Koe1, 1941Koe2, 1941Koe3, 1942Geb, 1942Koe, 1960Arn1, 1960Arn2]. After a gap of four decades, [1980Mur] reinvestigated the solid state equilibria, using 31 ternary alloys containing about 40.8 mass% Cu, in the temperature range of 250 to 350°C by means of metallography, X-ray diffraction and e...
