摘要

The work hardening mechanism and deformation behaviour of Hadfield steel crossing during explosion deformation were investigated by means of its ability to memorize the history of deformation and stress. The results show that the explosive stress causes little macroscopic distortion of the surface of the Hadfield steel crossing but higher work hardening degree, revealing an additional work hardening ability to compare with static deformation. Under the explosive deformation, the high strain rate results in much less strain threshold for inducing twin formation in Hadfield steel than that under static compression. During the explosive deformation, slipping and twinning are simultaneously operated in a competitive way. It is therefore concluded that the deformation twins are responsible for the additional work hardening of the Hadfield steel crossing subjected to the explosive treatment.
