liquidus|ˈlɪkwɪdəs|
[L. liquidus liquid a., adopted in this sense (in G.) by H. W. B. Roozeboom 1899, in Zeitschr. f. phys. Chem. XXX. 387.]
A line in a phase diagram, or a temperature (corresponding to a point on the line), above which a mixture is entirely liquid and below which it consists of liquid and solid in equilibrium; freq. attrib. as liquidus curve, liquidus temperature. Also (more fully liquidus surface), an analogous surface in a three-dimensional phase diagram.
1901Proc. R. Soc. LXVIII. 174 Cooling curves will..give the approximate moment of complete solidification of an alloy, and enable us to plot in a rough way the ‘solidus’ curve, as Roozeboom calls it; but the solidus curve thus obtained is not nearly so accurate as the ‘liquidus’ or freezing-point curve. 1923Glazebrook Dict. Appl. Physics V. 245/2 The liquidus and the solidus meet, in the case under consideration, at the points A and C, which are the melting points of the pure metals, and B, which is known as the eutectic point. 1948Glasstone Textbk. Physical Chem. (ed. 2) x. 762 Separation of solid..commences at y and is complete at z′; for this reason the liquidus curve is sometimes called the freezing-point curve, and the solidus curve is called the melting-point curve. 1960C. J. Phillips Glass: Industr. Applic. v. 54 The viscosity at the liquidus temperature is high enough to prevent nucleation. 1967A. H. Cottrell Introd. Metall. xvi. 252 (caption) Liquidus surface of a eutectic system. 1972Physics Bull. Nov. 352/3 Glass is a metastable state; it can be brought to the stable state by holding at temperatures near the liquidus. |
