Abstract
This study aims to investigate the healing method of internal cracks in 1045 steel. Real internal cracks were produced in 1045 steel specimens using plate impact technology successfully. A quasi in situ observation under scanning electron microscope and ultrasonic scanning was performed to investigate the behaviour of crack healing. After 120 min heat treatment at 1100 °C, the crack healing at crack tips was achieved. However, micro-voids were left in crack healing area and the edges of the remnant micro-voids were very smooth.
