eutectic
Americanadjective
-
of greatest fusibility: said of an alloy or mixture whose melting point is lower than that of any other alloy or mixture of the same ingredients.
-
noting or pertaining to such a mixture or its properties.
a eutectic melting point.
noun
adjective
-
(of a mixture of substances, esp an alloy) having the lowest freezing point of all possible mixtures of the substances
-
concerned with or suitable for the formation of eutectic mixtures
noun
-
a eutectic mixture
-
the temperature on a phase diagram at which a eutectic mixture forms
-
The proportion of constituents in an alloy or other mixture that yields the lowest possible complete melting point. In all other proportions, the mixture will not have a uniform melting point; some of the mixture will remain solid and some liquid. At the eutectic, the solidus and liquidus temperatures are the same.
-
An alloy or other mixture with constituents in the proportions of the eutectic.
-
The melting point of the eutectic.

On remelting, the temperature of solidification is found to be quite fixed, and the mixture is evidently eutectic.
From Scientific American Supplement, No. 508, September 26, 1885 by Various
From this diagram we should be led to expect a eutectic mixture, since the curve dips below a horizontal line passing through the melting-point of the more fusible of its constituents.
From Scientific American Supplement, No. 508, September 26, 1885 by Various
For an alloy of the composition of the eutectic itself there is no arrest until the eutectic temperature is reached, at which the whole solidifies without change of temperature.
From Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" by Various
It will be seen at once by this definition that the temperature of liquefaction of a eutectic substance is lower than the temperature of liquefaction of either or any of the constituents of the mixture.
