eutectic system
1Eutectic point — The melting point of a mixture of two or more solids (such as an alloy) depends on the relative proportions of its ingredients. A eutectic or eutectic mixture is a mixture at such proportions that the melting point is as low as possible, and that …
2eutectic — upon cooling, a liquid phase transforms isothermally and reversibly into two intimately mixed solid phases; the lowest melting composition in a material system …
3Thermal energy storage — District heating accumulation tower from Theiss near Krems an der Donau in Lower Austria with a thermal capacity of 2 GWh Thermal energy storage comprises a number of technologies that store thermal energy in energy storage reservoirs for later… …
4Fractional freezing — is a process used in process engineering and chemistry to separate two liquids with different melting points. It can be done by partial melting of a solid, for example in zone refining of silicon or metals, or by partial crystallization of a… …
5Hypoeutectic alloy — A hypoeutectic alloy is a binary alloy in which the composition is to the left hand side of the eutectic point on the equilibrium diagram of a binary eutectic system. At any position where the hypoeutectic alloy exists the solute concentration at …
6cryohydrate — A eutectic system of a salt and water. * * * cryo·hy·drate (kri″o hiґdrāt) [cryo + hydrate] 1. a salt containing water of crystallization at low temperatures. 2. a eutectic mixture, especially one having water as one of its… …
7phase — phaseless, adj. phasic, phaseal, adj. /fayz/, n., v., phased, phasing. n. 1. any of the major appearances or aspects in which a thing of varying modes or conditions manifests itself to the eye or mind. 2. a stage in a process of change or… …
8Type metal — The term type metal (sometimes called hot metal ) represents a range of metal alloys that are used in traditional typefounding and mechanical typesetting. History Although the knowledge of casting soft metals in moulds was well established before …
9Casting (metalworking) — Casting iron in a sand mold In metalworking, casting involves pouring liquid metal into a mold, which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The solidified part is also known as a casting, which… …
10Soldering — For the song, see Soldering (song). For the product, see Solder. Desoldering a contact from a wire. Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal (solder) into the joint, the… …
