Dilatometry
Dilatometry is the measurment of thermal expansion. Mechanical dilatometer facilities are available for the measurement of fractional length change as a function of temperature, from which the derived mean linear expansion coefficient over a temperature range or the ‘expansivity’ at a given temperature can be computed. Effects such as annealing or softening temperatures can be determined. Phase changes can be detected, and the magnitude of their effect on overall dimensions determined.
Key Information
