A two-dimensional graph that shows the state, or phase, of a substance at any combination of temperature and pressure.
phase map. A map that shows which phases of a sample are most stable for a given set of conditions. Phases are depicted as regions on the map; the borderlines between regions correspond to conditions where the phases can coexist in equilibrium.
Graphical representation of temperature phases in an alloy. A tin/lead phase diagram (that is, solder) shows solidus and liquidus temperatures for a range of tin/lead proportions.
a graphical representation of the vapor pressures of the solid and liquid forms of a substance.
Phase diagram is a graphical representation of the equilibrium relationships between phases (such as vapor-liquid, liquid-solid) of a chemical compound, mixture of compounds, or solution.
a graphical diagram on which the boundaries between different solid phases and between solids, liquids and gases, representing chemical reactions are shown.
is the P-T diagram of a pure substance and shows all three phases separated from each other by the sublimation line, vaporization line, and melting line.
a concise expression of many chemical equations and equilibria that occur in a system of several components
a graphical way to depict the effects of pressure and temperature on the phase of a substance
a graphic representation of phase equilibria with a one to one geometrical correspondence with the phase rule
a graph showing the limiting conditions for solid, liquid, and gaseous phases of a single substance or of a mixture of substances while undergoing changes in pressure and temperature or in some other combination of varia
a plot of one system variable versus another which shows the conditions at which the substance is a solid, liquid, gas, or s
a plot of pressure ( P or ln P ) vs
a plot of pressure ( P ) vs temperature ( T ) in which
a set of curves drawn in relation to a set of coordinate axes where pressure, p , is plotted on the vertical axis and temperature, T , is plotted on the horizontal axis
a graphical representation of the relationships between environmental constraints, composition, and regions of phase stability, ordinarily under conditions of equilibrium.
graphical representation of the regions and boundaries of existence for different phases - as states of aggregation - belonging to a given physico-chemical system in dependence of two or more thermodynamic quantities, e.g. temperature, pressure, concentration
Graph of temperature and pressure showing the range of each under which a given material can exist in the solid, liquid or vapor phases.
Diagram that shows equilibrium temperature-pressure relationships for different phases of a substance.
(1) A graphic representation of the equilibrium temperature and composition limits of phase fields reactions in an alloy system. In a binary system, temperature is usually the ordinate and composition the abscissa. Ternary and more complex systems require several two-dimensional diagrams to show the temperature-composition variables completely. In alloy systems, pressure is usually considered constant, although it may be treated as an additional variable. (2) Graphical representation of the equilibrium temperatures and the composition limits of phase fields and phase reactions in an alloy system.
In physical chemistry, mineralogy, and materials science, a phase diagram is a type of graph used to show the equilibrium conditions between the thermodynamically-distinct phases. In mathematics and physics, a phase diagram also has an alternative meaning, as a synonym for a phase space.
