Description

We studied electromagnetic acoustic resonance at elevated temperatures up to 1000 K. Using Lorentz-force transduction, we measured the temperature dependence of resonant frequencies and attenuation coefficients in SiC-fiber-reinforced Ti-alloy composites. Evolution of the resonance frequencies is consistent with the changes of elastic constants of the matrix, and attenuation evolution is explained by dislocation damping in the matrix.

Electromagnetic Acoustic Resonance of SiCf/Ti Composites at Elevated Temperatures
