| Abstract: | The effect of plastic deformation of a 08Kh18N10T (analogue AISI321)-steel welded joint on electromagnetic and acoustic properties of the material has been studied by eddy-current and ultrasonic methods. It has been established that structural inhomogeneity in heat- affected zone leads to a nonuniform distribution of acoustic properties in the weld. The possibility for determining the plastic resource of material from ultrasonic data is demonstrated. |
