Non-destructive surface characterization of carburized steel using Rayleigh waves
as a function of frequency, was calculated from the recorded
by plotting phase velocity versus wavelength/residual case
carbon content and hardness value. Dispersion was observed
depth ratio. A linear fit was applied to the data with
displacement-time waveforms. The phase velocity was lower in
fit, it would be possible to non-destructively estimate case
gradients, such as carburized steel, for depth of the surface
interferometer. Experimental dispersion data, phase velocity
Rayleigh waves which were detected with a fiber optic based
surface acoustic waves to interrogate materials with property
the carburized case of the material which has a greater
The research described in this thesis involves the use of
treatment. A 3.5 MHz wedge transducer was used to generate
wavelength/residual case depth less than 2, and using this
