2023年7月12日 · The eutectic point is a unique temperature at which a combination of different substances melts or solidifies simultaneously. This temperature is the lowest possible melting point that the mixture can attain, lower than any of the substances’ individual melting points.

The eutectic point is when a solid solute, a solid solvent, and a liquid mixture all exist in the same phase. The eutectic point is the lowest temperature at which the liquid phase is stable at a given pressure.

2019年7月14日 · Sodium chloride and water form a eutectoid when the mixture is 23.3% salt by mass with a eutectic point at -21.2 degrees Celsius. The system is used to make ice cream and to melt ice and snow. The eutectic point of the mixture of ethanol and water is nearly pure ethanol.

The eutectic melting point is at 780 °C, with solid solubility limits at fineness 80 and 912 by weight, and eutectic at 719. Since Cu-Ag is a true eutectic, any silver with fineness anywhere between 80 and 912 will reach solidus line, and therefore melt at least partly, at exactly 780 °C.

2023年11月14日 · The binary eutectic phase diagram has several distinctive features one being a solid-solid phase mixture, limit of solubility at different temperatures, and an invariant point in the phase diagram, the eutectic point.

2023年1月16日 · Figure \(\PageIndex{3}\): A simplified phase diagram of a two-component system that exhibits an eutectic point. In this diagram, the vertical boundary at \(\chi_B = 0.33\) is indicative of the compound \(C\) formed by \(A\) and \(B\).

The eutectic point is an important concept in materials science and metallurgy, as it determines the behavior of alloys and other complex systems. For example, in a binary phase diagram, the eutectic point represents the composition at which two solid phases coexist with a liquid phase.

The eutectic point is the point on the phase diagram where the maximum number of the allowable or considered phases are stabilised in an equilibrium. When this point is reached, the temperature should remain constant until one of the phases disappears.

The eutectic system in phase transition is a homogeneous mixture of solids but has a different melting point or solidification point than the individual components. Usually, the eutectic point is the lowest point or temperature at which the substance freezes or melts in a eutectic mixture.

Point B is the eutectoid point, and 727°C is the eutectoid temperature, the invariant temperature. Alloy of composition of point B is called eutectoid alloy (0.77% carbon steel is eutectoid steel).
