Abstract:

The velocity of a Rayleigh wave was determined on 3-5 mm bases by measuring the changes in the distance between a transducer attached to an object and a laser-irradiated surface area. The propagation time of the wave from the transducer to this area was simultaneously measured. The distance and time were determined with resolutions of 0.1 mu m and 1 ns, respectively. The setup was tested for plastically strained 45 steel specimens subjected to uniaxial tension. It was shown that the velocity measurement error is no larger than +/- 1\% and that the correlation coefficient between the Rayleigh wave velocity and microscopic distortions in the crystal lattice is 0.89.
