The proportion of metals in an alloy that results in the lowest possible melting point for that alloy. In tin/lead solders, the eutectic is 63%Sn/37%Pb.
A mixture of two or more constituents which solidify simultaneously out of the liquid at a minimum freezing point.
Characteristic of a mixture having the lowest possible melting point of two or more constituents which melt completely at a definite temperature to form a single liquid.
The lowest melting point of two or more substances.
(das) Eutektikum Etymology: griech. ευ 'eu': good and τεκτειν 'tektein': build. An alloy is eutectic when the proportions of the components are such that the alloy is above a given →melting point liquid (→Liquidus temperature) and below the same temperature ( solidus temperature) completely solid. The eutectic is reached when both points fall together, the eutectic point. This is usually the lowest melting point of any proportion of components. Since this alloy will solidify almost instantly at a given temperature a fine grained and uniform microstructure is produced.
1) An isothermal reversible reaction in which a liquid solution decomposes, on cooling, into two or more intimately mixed solids. The number of solids formed are the same number of components in the system. 2) An alloy having the chemical composition indicated by the eutectic point on a equilibrium diagram.
An alloy of two or more metals that has a lower melting point than either of its constituents. The alloy can pass (reversibly) from solid into the liquid state without an intermediate plastic phase. Eutectic tin-lead solder is usually regarded as having the proportion 63% tin to 37% lead.
an equilibrium phase transformation in which a single phase liquid transforms to two different solid phases on cooling through the invarient temperature
The lowest solidification temperature of an alloy or a metal. Also defined as the point at which metal goes most directly from liquid to a solid.
This phenomenon occurs when two dissimilar fats are melted, blended together and re-crystallized, the resultant mixture will melt at a lower temperature than either of the components.
A eutectic system occurs when a liquid phase tramsforms directly to a two-phase solid.
A thermodynamic isothermal reversible reaction in which a liquid is converted into two or more intimately mixed solids. When cooled, the number of solids formed is the same as the number of components in the system. An alloy that has the composition indicated by the eutectic point on a equilibrium diagram. An alloy structure of intermixed solid constituents formed by a eutectic reaction.
An alloy of two or more metals where the liquidus and solidous points are equal.
A mixture of substances that has a melting point lower than that of any mixture of the same substances in other proportions.
The lowest melting mixture of two or more ceramic substances. This is always lower then the melting points of the individual materials.
The mixture of two or more components whose melting point is lower than that of any individual component.
(1) An isothermal reversible reaction in which a liquid solution is converted into two or more intimately mixed solids on cooling, the number of solids formed being the same as the number of components in the system. (2) An alloy having the composition indicated by the eutectic point on an equilibrium diagram. (3) An alloy structure of intermixed solid constituents formed by a eutectic reaction.
The minimum melting point of a combination of two or more metals.
An alloy composition which exhibits the lowest melting temperature possible within that system; has a melting point, not a melting range.
That certain mixture of two substances providing lowest melting temperature of all the various mixes of the two substances.
In certain ranges of metal alloys there is one is mixture which melts at a lower temperature than any other alloy in the series. Such an alloy is termed the eutectic.
Upon cooling, a liquid phase transforms isothermally and reversibly into two intimately mixed solid phases; the lowest melting composition in a material system.
An alloy with a melting point lower than that of any other combination of the same components; an alloy used as a fuse element to detect and protect against high damaging environmental temperatures' a fuse element used to monitor long overload conditions on a transformer by melting when a combined temperature (top oil temperature rise due to loading plus temperature rise due to current passing through element proper) equal to the fuse's melting temperature is achieved.
The invariant point for a substance at which change, either with the addition or removal of heat, results in an increase or decrease of the proportion of liquid to solid phases, without change in temperature.
The point in the state diagram of an alloy consisting of several fully mixable alloy components at which the alloy has the lowest possible melting point e.g. Eutectic system of a lead-antimony alloy: Pb:Sb = 88.9:11.1 with melting temperature TEutectic = 252° C.
In alloy systems with eutectics, this can be the lowest melting point phase and so the last to solidify when casting. In Al-Si casting alloys, the eutectic is often modified to alter its structure to enhance ductility.
Alloy that is created by the proportion of combined elements yielding the lowest melting point of any of the proportions. For example: solder.
A Eutectic is a mixture of two fats (or any other substances) in which the physical characteristics (i.e. setting point, melting point, etc.) are lower than those of the components.
