Tie line phase diagram. The percentages of the two components in each phase enable the composition of that phase to he represented by a point on triangular coordinates. The points for equilibri- um pairs of phases are the ends of the tie line for that sys- tem. When these are all plotted, the phase diagram c % If the entire length of the tie line mo is taken to represent 100% or the total weight of the two phases present at temperature T, the lever rule may be expressed mathematically as: For such phase diagram, there is one degree of freedom. So, in this case Gibb’s rule converts into Binary phase diagrams. Before any calculations can be made, a tie line is drawn on the phase diagram to determine the mass fraction of each element; on the phase diagram to the right it is line segment LS. This tie line is drawn horizontally at the composition's temperature from one phase to another (here the liquid to the solid). 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).

An isothermal (constant temperature) line through the alloy's position on the phase diagram when it is in a two phase field, intersecting the two adjacent solubility curves, is called a tie line (yes, that's the horizontal yellow line on the diagram).. The ends of the tie lines show the compositions of the two phases that exist in equilibrium with each other at this temperature. An isothermal (constant temperature) line through the alloy's position on the phase diagram when it is in a two phase field, intersecting the two adjacent solubility curves, is called a tie line (yes, that's the horizontal yellow line on the diagram). Click to see full answer. 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 ... -q-line-Phase diagram for constant relative volatility •AzeotropicSystems.
