AbstractPre-cracked C-Mn Steel weld metal specimens were shack-treated (with a peak pressure of 5 GPa). The fracture behavior of the shock-treated specimens and the microstructure around the pre-crack tip were investigated. The results show that the shock-treated specimens have significantly increased fracture resistance ability at various test temperatures. A softening fine grain zone was found around the pre-crack tip. It was believed that the softening fine grain zone: was formed during the adiabatic shearing process when shock waves pass through the specimen. The zone around the pre-crack tip is suggested to play an important role in influencing the fracture behavior of the shock-treated specimen. (C) 2000 Elsevier Science S.A. All rights reserved.
