Correlation of acoustoelasticity with hydrogen saturation during destruction

Correlation of acoustoelasticity with hydrogen saturation during destruction

The surface effect of acoustic anisotropy in steel and aluminum industrial alloys was experimentally detected. Changes in the integral value of acoustic anisotropy in 10–15 times were observed after removing the surface layer with a thickness of 100 microns in steel specimens and 250 microns in alum...
