Abstract
The results of experimental estimates of the attenuation of Rayleigh waves as a function of the surface stresses in gray iron are presented. A treatme nt of the mechanism by which the attenuation of ultrasound depends on the s tresses is proposed. The relations found indicate the possibility, in princ iple, of designing instruments for estimating stresses, including residual stresses, in the components of machines and mechanisms made of gray iron fr om the value of the attenuation of ultrasonic Rayleigh waves.
