Abstract
Specimens of 1045 steel with quenched crack were treated under electropulsi
ng. Scanning electron microscopy was employed to examine the change of spec
imens before and after the treatment. The results showed that the crack can
be healed under electropulsing without melting, and the healing could be p
roduced within a very short time. The original microstructure of specimens
was not changed during the healing. It is thought that the temperature and
the transient thermal compressive stress caused by high-rate heating are th
e main factors causing the healing of the crack.
