ABSTRACT:
A method and apparatus for determining the freezing points of a metal by inducing solidification in a cooling liquid metal sample in a supercooled state and utilizing specific detected peak values or changes in slope in a temperature/time plot as the sample cools, begins solidification and recalesces. It was found that the maximum temperature reached after the second rise, if two rises occur, the maximum of a single rise, or the temperature at which the rate of temperature drop decreases, if no temperature rise occurs, provides a useful approximation of the liquidus temperature and hence the freezing point of the sample.
