Abstract
Photoacoustic and photothermal techniques which can be used for the investigation and imaging of solids with residual stresses are described. Photoacoustic and photothermal images of different types (photodeflection, photoreflectance, photoacoustic piezoelectric) are presented. By imaging Vickers indented samples it is demonstrated that the photoacoustic piezoelectric microscopy has a high sensitivity to residual stresses. It is also shown that thermal wave images do not reveal a strong influence of residual stress on thermophysical properties of materials. Presented results of the photoacoustic and photothermal imaging of samples under direct loading and annealing demonstrate some specific features of the residual stress influence on the photoacoustic signals. The possibility of development of new non-destructive evaluation systems based on application of modern lasers for residual stress detection is discussed.
