Abstract The in-situ observation of hydrogen-attacked cracks healing in carbon steel had been done by high-temperature microscope.The whole cracks healing process was recorded at the same time.The results show that the c racks became obviously thinner when heated under 630℃.The escaping of methane a nd inner crack exposure on specimen surface make a certain difference between th is experiment and true condition,the analysis indicates the cracks healing tempe rature in experiment is lower than actual system.The healing of hydrogen attacke d cracks is closely related to heat diffusion of Fe and C atoms in steel.The dri ving force of crack healing results from the plastic deforming energy Es i nduced by the growth of hydrogen attacked bubbles or cracks.The critical conditi on of healing of bubbles or cracks is Es ≥2γ/r (where γ is the surface tension,r is the radius of bubbles or half length of crack).

Key words: high-temperature microscope in-situ hydrogen attack crack healing
