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. Line in the phase diagram of an alloy system (Fig. 1) connecting all solidus temperatures and delimiting the temperature range in which the melt is only ... The phase diagram consists of two points, two lines, and three areas. The two points T A and T B represent the freezing points of the two pure metals. 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).

The tie line on a two-component solid- liquid phase diagram is an isothermal line that connects two equilibrium phases and passes through the alloy's position on the phase diagram when it is in a two-phase field, which intersects the two adjacent solubility curves. ... Note where the tie line intersects the liquidus and solidus lines (i.e ... A typical phase diagram. The solid green line applies to most substances; the dotted green line gives the anomalous behavior of water. The green lines mark the freezing point and the blue line the boiling point, showing how they vary with pressure. 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. The phase diagram for the Gd-Dy system as presented by Markova et al. showed six data points that formed a smooth curve defining the solidus of the system. This solidus has a slight downward curvature and the liquidus was drawn as a dashed straight line that connected the melting points of the end-members.

This is referred to as the solidus temperature, and the solidus line describes this temperature at varying compositions. The liquidous line describes the temperature at which the last little bit of solid melts at varying compositions. The eutectic line is a horizontal line drawn between two one-phase fields a the eutectic temperature. 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. Sign in to download full-size image 1.14. The solidus line (dotted line in Fig. 1) in the Sn-rich side of the Sn-In phase diagram remained indeﬁnite until now. It was determined by measuring the chemical composition of solid-phase grains in samples annealed at different temper-atures in the (liquid + c) two-phase region. The composition possible compositions of the alloy. The equilibrium "phase diagram" opposite shows the dependence of the alloys melting point on its composition, and the existence of the single solid phase below the solidus line indicates the complete solid state miscibility of the two elements.

As solidus line is a continuous line connecting the melting points of pure metals, the complete solidus line is MFGN. The phase diagram consists of four areas. The area above the liquidus line is a single-phase homogeneous liquid solution, since the two metals are soluble in the liquid state (labeled as Liquid solution).

The solvus is represented by a line on a phase diagram that separates a solid phase from a solid1 + solid2 phase, where solid1 and solid2 are different microstructures. The eutectic is represented by the horizontal line in a eutectic binary phase diagram, connecting the intersections of the solidus and solvus lines from both sides. The eutectic temperature also is where the liquidus lines for both components meet.

John F. Smith, in Methods for Phase Diagram Determination, 2007. Publisher Summary. It was recognized that the terminal solubilities of impurities in a material differ between the liquid and solid states. In a phase diagram, this would be indicated by the separation between the liquidus and solidus lines. The fact that industry believes in the importance of phase diagrams is proven by the fact that industrial funding made the alloy phase diagram program possible.
