38 solidus line phase diagram

In Cigar shape diagram there are three different regions: 1. Liquid (single phase) 2. Liquid + solid (double phase) 3. Solid solution (single phase) •Liquidus- the boundary line between the liquid region and the double phase region. •Solidus- the boundary line between the solid solution region and the double phase region. Interpretation of Binary Phase Diagram - Using Phase Rule, Tie-Line and Lever Rule For a binary system of known composition and temperature that is at equilibrium, at least three kinds of information are available: (1) the phases that are present, (2) the compositions of these phases, and (3) the percentages or fractions of the phases. For determining the degrees of freedom in a binary phase ...

Solidus line phase diagram

Solidus: The solidus line is a line on a phase diagram, below which a substance acts as solid. It is the locus of temperature below which it is only characterized by solid. The solid is characterized by large intermolecular forces. Liquidus: It is a line in the phase diagram above which is characterized by only liquid. Intermolecular forces are ... 1. Locate composition and temperature in diagram . 2. In two phase region draw the tie line or isotherm . 3. Fraction of a phase is determined by taking the length of the tie line to the phase boundary for the other phase, and dividing by the total length of tie line . The lever rule is a mechanical analogy to the mass balance calculation. The ... The phase diagram, therefore, consists of a liquidus line showing a minimum at the eutectic temperature, which is itself marked by a horizontal line. Since the solid phases formed consist simply of pure cadmium or pure bismuth, the solidus lines are coincident with the two vertical temperature axes. 1.14.

Solidus line phase diagram. In chemistry, materials science, and physics, the solidus is the locus of temperatures (a curve on a phase diagram) below which a given substance is completely solid (crystallized). The solidus temperature, T S or T sol, specifies the temperature below which a material is completely solid, and the minimum temperature at which a melt can co-exist with crystals in thermodynamic equilibrium. Binary phase diagrams are important tools for designing desired alloys. In the Sn-rich region of the Sn-In alloy phase diagram, the solidus line appears as a dotted line in current literature plots to indicate uncertainty. The contour of the solidus has now been clarified as a result of the present investigation. Four alloys, Sn70In30, Sn75In25, Sn80In20, and Sn85In15 were melted at 300 °C ... phase diagram A(1100, 60): 1 phase: B(1250, 35): 2 phases: L + Determination of phase(s) present Melting points: Cu = 1085°C, Ni = 1453 °C Solidus - Temperature where alloy is completely solid. Above this line, liquefaction begins. Liquidus - Temperature where alloy is completely liquid. Below this line, solidification begins. In particular, the solidus line defines the temperature below which the phases in the diagram are solid, while the liquidus line defines the temperature above which the phases are completely liquid. The Zr-Sn phase diagram depicted in Fig. 1.5 is a very relevant system in the context of light water reactors (LWRs), as one of the chosen ...

The solid solubility of Bi in Cu single crystals has been experimentally determined. It is shown that the solidus line is a retrograde curve without a monotectic transition. The solid and liquid phases are successfully described with simple thermodynamic models. The experimentally measured maximum solubility of 0.0207 at. % Bi at 975 °C correlates well with that from the model (0.0193 at ... in 2-phase region: 1. Draw the tie line. 2. Note where the tie line intersects the liquidus and solidus lines (i.e. where the tie line crosses the phase boundaries). 3. Read off the composition at the boundaries: Liquid is composed of CL amount of Ni (31.5 wt% Ni). Solid is composed of Cαααα amount of Ni (42.5 wt% Ni). Area above the liquidus line is single phase region and any alloy in that region will consist of homogeneous liquid solution. Similarly, lower region is homogeneous in nature. In between the solidus and liquidus line there exist a two phase region. It is the mixture of both solid and liquid, it is mushy in type. The simplest phase diagrams are pressure-temperature diagrams of a single simple substance, such as water.The axes correspond to the pressure and temperature.The phase diagram shows, in pressure-temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas.. The curves on the phase diagram show the points where the free energy (and other ...
