摘要：

Thermal diffusivity is measured applying three techniques: (a) thermal wave generation by thermoelectric device; (b) non-adiabatic flash method with correction for non-ideal Dirac pulse by deconvolution; (c) photothermal deflection. They are applied on a sample of AISI 304. Results are compared with those obtained by the standard laser flash method. (C) 21002 Published by Elsevier Science B.V.
