  2. Cooling curve - Wikipedia

    en.wikipedia.org/wiki/Cooling_curve

    A cooling curve of naphthalene from liquid to solid. A cooling curve is a line graph that represents the change of phase of matter, typically from a gas to a solid or a liquid to a solid. The independent variable (X-axis) is time and the dependent variable (Y-axis) is temperature. [1] Below is an example of a cooling curve used in castings.

  3. Continuous cooling transformation - Wikipedia

    en.wikipedia.org/wiki/Continuous_cooling...

    There are two types of continuous cooling diagrams drawn for practical purposes. Type 1: This is the plot beginning with the transformation start point, cooling with a specific transformation fraction and ending with a transformation finish temperature for all products against transformation time for each cooling curve.

  4. Thermodynamic diagrams - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_diagrams

    The main feature of thermodynamic diagrams is the equivalence between the area in the diagram and energy. When air changes pressure and temperature during a process and prescribes a closed curve within the diagram the area enclosed by this curve is proportional to the energy which has been gained or released by the air.

  5. Phase diagram - Wikipedia

    en.wikipedia.org/wiki/Phase_diagram

    A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct phases (such as solid, liquid or gaseous states) occur and coexist at equilibrium.

  6. Thermal analysis - Wikipedia

    en.wikipedia.org/wiki/Thermal_analysis

    This procedure is known as Computer-Aided Cooling Curve Thermal Analysis. [4] Advanced techniques use differential curves to locate endothermic inflection points such as gas holes, and shrinkage, or exothermic phases such as carbides, beta crystals, inter crystalline copper, magnesium silicide, iron phosphide's and other phases as they solidify.

  7. Isothermal transformation diagram - Wikipedia

    en.wikipedia.org/wiki/Isothermal_transformation...

    TTT diagram of isothermal transformations of a hypoeutectoid carbon steel; showing the main components obtained when cooling the steel and its relation with the Fe-C phase diagram of carbon steels. Austenite is slightly undercooled when quenched below Eutectoid temperature. When given more time, stable microconstituents can form: ferrite and ...

    Though Ray admits he’s wary of his sons pursuing careers in entertainment — “It’s an industry full of failure,” he says — he’s supportive as long as they’re following their passions.

  9. Supercooling - Wikipedia

    en.wikipedia.org/wiki/Supercooling

    Supercooling is the cooling of a liquid below its freezing point without it becoming solid. Freezing point depression is when a solution can be cooled below the freezing point of the corresponding pure liquid due to the presence of the solute; an example of this is the freezing point depression that occurs when salt is added to pure water.
