Test measurements of the photothermal deflection method to determine the thermal diffusivity of solids.
The photothermal deflection spectroscopy method is employed in thermal diffusivity measurements of solids. Thermal diffusivity at room temperature in standard materials such as Poco-graphite and S.S. 1.4970 stabilized austenltlc steel Is measured and compared with the tabulated values.
