Abstract
A thermocouple formed of a length of a single composition having first solid phase section adjoining a second solid phase section, and a transition therebetween. One method of making such thermocouples is to raise the temperature of the first solid phase section above its transformation temperature while maintaining the temperature of a second adjoining solid phase section of the length of material below its transformation temperature. A second method includes rapidly solidifying a molten material by contacting it with a moving substrate formed of adjoining regions of differing thermal conductivity. A third method includes rapidly solidifying a molten material by alternatingly contacting it with a cooling fluid and air. A fourth method includes transforming a section of a length of material in a first solid to a second solid phase by mechanical means.
