| Summary: | Title screen The basic regularities of the 17MnSi pipeline steel impact fracture without and after the ultrasonic impact surface treatment were identified. The diagrams of the material dynamic deformation which allowed determining quantitative characteristics of the crack initiation and crack propagation energy consumption in the Charpy specimens of the pipeline steel were analyzed. The crack was found out to correspond approximately to 25 % of the total energy consumption of the material fracture. The fractographic analysis of the specimen failure surfaces in the initial state and after the ultrasonic treatment was carried out. |
