Research Abstract

The fracture behavior transition due to the change of strain rate in 5%Si magnetic steel with dislocation microstructures was studied. The Si steel was multi-passed rolled at 1073K to a various reduction up to 50%. The every rolled steels were fractured in ductile manners with necking at slower strain rate. When strain rate was faster, the local elongation (necking) disappeared and the fracture manner was changed to brittle. The strain rate at which fracture mechanism changed from ductile to brittle increased with the increasing of the reduction. This result indicates that dislocation structure is effective for the enhancement of toughness in Si steel.
