It is shown that the solidus line is a retrograde curve without a monotectic transition. Similarly, lower region is homogeneous in nature. The solidus line (dotted line in Fig. Read off the composition at the boundaries: Liquid is composed of CL amount of Ni (31.5 wt% Ni). Journal of Phase Equilibria Vol. > and liquid + > and + >Liquid + and liquid + >Liquid and liquid + A solidus line separates which of the following phase fields? Following is wrong about a phase diagram. grains. Binary Metal System, Cadmium, Zinc, Tellurium, Phase Diagram, Solidus Line, Eutectic Transformation, Retrograde Solubility 1. A binary phase diagram is a temperature - composition map which indicates the equilibrium phases present at a given temperatureandcomposition. On the phase diagram, the value of either \(T\) or \(p\) has been fixed, so there are two other independent intensive variables. 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. Introduction The investigation of the equilibrium phase transformation in the twocomponent metal systems is among the - main problems of materials science. Liquid + solid (double phase) 3.

Phase Diagram - All compositions above the liquidus line are liquid, and those below the solidus line are solid. •The tie‐line method works for the liquid phase, where diffusion is fast. Above the liquidus line the system is entirely molten and below the solidus line it is entirely solid. Liquidus is a see also of solidus. Solidus - The line separating the field of all solid from that of liquid plus crystals. It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line. A common example is Ice and Salt. Similarly, the area below the solidus line is a single-phase region, and any alloy in this region will consist of a homogeneous solid solution. Solid solution (single phase) •Liquidus- the boundary line between the liquid region and the double phase region. liquidus and solidus curves are tangent to each other and at a constant temperature line … The contour of the solidus has now been clarified as a result of the present investigation. By drawing a vertical line based on the intersection points to the concentration axis, the corresponding chemical composition of the melt and the solid solution can now be read off directly. Technically it is "the locus of temperatures below which only solid is stable". The paper presents the calculation results on the construction of solidus lines of phase diagrams for some binary metal systems based on cadmium, zinc and tellurium. Chang, B.B.
