Abstract

To measure residual elastic stresses in the surface layers of recrystallized commercially pure α-Ti before and after the shock-wave action of a picosecond laser pulse, which leads to nanostructuring of a thin surface layer, a method of correlating images of rectangular cross-section depressions (slots) cut by a focused ion beam in the column of a scanning electron-ion microscope is used. It is suggested that laser treatment helps to relieve residual stresses in the surface layers of the studied sample.
