A homogeneous thermoelastic heat source is fed, in a cylindrical sample, by compression; the amount of generated heat is controlled by the Gruneisen parameter. The heating process is followed by a thermal relaxation controlled by the thermal diffusivity. The temperature transient is detected by a miniature temperature sensor mounted on the lateral surface of the sample. Measurements are performed on a technological steel.

Abstract
A homogeneous thermoelastic heat source is fed, in a cylindrical sample, by compression; the amount of generated heat is controlled by the Gruneisen parameter. The heating process is followed by a thermal relaxation controlled by the thermal diffusivity. The temperature transient is detected by a miniature temperature sensor mounted on the lateral surface of the sample. Measurements are performed on a technological steel.File in questo prodotto:
