Abstract

Using the open photoacoustic cell technique, we obtained the spectra of the photoacoustic signal amplitude as a function of the modulation frequency of the incident radiation. From these spectra we determined the thermal diffusivity in Mg- AZ91E/AlN metal matrix composite with a magnesium alloy of around 9% aluminum and 1% zinc, the aluminum nitrade (AlN) is a ceramic with relationship AlN/AZ91E with ratio 1:1. The photoacoustic signal amplitude in the region thermally thick and optically opaque is used to calculate the thermal diffusivity of the Mg-AZ91E/AlN material and the results obtained are shown.
