Voorbeelden van critical temperature

• Furnace annealing is much better and consists in heating the piece in a furnace to the critical temperature and then allowing the work and the furnace to cool together. 

• Here, too, there were no seas, for the temperature was above the critical temperature of water, and only in the self-cooling bodies of these men and in the trees which similarly cooled themselves, could there be liquid. 

• Its critical temperatures will be located at slightly different heats than for a steel which has a different proportion of alloying elements. 

• The critical temperatures are the proper ones for annealing as well as hardening. 

• This condition implies that at the critical temperature the magnitude of the initial order parameter does not exceed its value at the superconducting state at temperature absolute zero.

• Tempering is accomplished by controlled heating of the quenched work-piece to a temperature below its lower critical temperature.

• Both types of motion occur because metal first expands in a fire, and then softens once the critical temperature has been reached, as is explained under structural steel.

• A rough estimate of the critical temperature was possible either with experience or on the basis of some trial runs made with larger temperature steps.
