cooling curve

Cooling curves are important in controlling the quality of a casting.

Below is an example of a cooling curve used in castings.

A cooling curve is plotted and the freezing point determined.

Brad and left the cooling curve for an entire universe on the projector, his death marked in red.

The "cooling rate" is the slope of the cooling curve at any point.

For every year after that, we lose more ground; by the end of five years, the destructive cooling curve rises rapidly towards catastrophe.

The cooling curves corresponding to mixtures with compositions a, b and c are shown in figure 6.30.

The most important part of the cooling curve is the cooling rate which affects the microstructure and properties.

Temperature -composition phase diagrams for solid-liquid systems can be constructed from cooling curves.

Below is an example cooling curve of a pure metal or eutectic alloy, with defining terminology.

Figure 6.28 shows the cooling curves for pure benzene, pure naphthalene and a mixture of the two.

T is located at the intersection between the cooling curve (volume versus temperature) for the glassy state and the supercooled liquid.

Losses are reduced by maintaining a closer match between the brine cooling curve and the working fluid heating curve.

The cooling curve of a small steel sample can be analyzed and used to estimate the carbon content of molten steel.

To do so, the cooling curves are plotted for the two pure components and for mixtures with various compositions of the two components.

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.

Type 1: This is the plot of transformation start, a specific transformation fraction and transformation finish temperature for all products against transformation time on each cooling curve.

For this reason it may not be correct to relate thermodynamic quantities obtained from one cooling curve to those obtained by another as has been pointed out by Gee (1966).

The above cooling curve depicts a basic situation with a pure alloy, however, most castings are of alloys, which have a cooling curve shaped as shown below.

Strictly speaking these measurements are cooling curves and a form of sample controlled thermal analysis whereby the cooling rate of the sample is dependent on the cup material (usually bonded sand) and sample volume which is normally a constant due to the use of standard sized sample cups.
