Dynamic Impact and Fracture Toughness of 16MnR Welded Joints

  • Publish Date: 25 Oct 2003
  • The dynamic impact energies of 16MnR welded joints were determined with high speed impact test, and the influencing factors and fracture morphology were studied. The impact toughness of 16MnR welded joints decreases greatly and the joints become brittle in general with an increase in impact speed. The results suggest that more attention should be paid to the dynamic impact toughness of a welded joint when it is subjected to high speed impact loads.
