Implication

Experimental study demonstrates rapid measurement of thermal diffusivity across metals from 0 to 500°C, highlighting improved reliability and simplified computation for high-temperature testing.

Key Points

To develop a faster and more reliable dynamic method for determining the thermal diffusivity and conductivity of metals at elevated temperatures.
Applied a sinusoidally varying heat pulse to one end of an effectively infinite metal rod.
Measured both pulse velocity and amplitude decrement over a single period using amplified thermoelectric potentials from two thermojunctions to eliminate radiation heat loss parameters.
Evaluated the technique on copper, nickel, and thorium specimens across temperatures ranging from 0°C to 500°C.
Demonstrated that a single heat pulse period provides sufficient data to cancel radiation loss coefficients, simplifying computation and improving high-temperature reliability.
Successfully determined thermal diffusivity profiles for copper, nickel, and thorium throughout the 0–500°C operating range.
