Abstract
A system for determining a neutral temperature of a metal specimen includes an excitation assembly disposed adjacent to the metal specimen for inducing vibrations to the metal specimen, at least one vibration detector disposed adjacent to the metal specimen to measure the induced vibrations transmitted in the metal specimen, a temperature sensor disposed adjacent to the metal specimen to measure temperature of the metal specimen, and a control/acquisition system for control of the excitation assembly and acquisition of data from the excitation assembly, the at least one vibration detector, and the temperature sensor, wherein the control/acquisition system calculates damping coefficients for each of the induced vibrations and determines a peak damping coefficient corresponding to the neutral temperature of the metal specimen based upon the acquired data.
