%X The effects of environmental media, both in atmosphere and in 3.5% NaCl aqueous solution, on the growth of short cracks in comparison with the long ones have been investigated under fatigue loading on the specimens of single- edge crack about 0.05--0.15 mm for A537CL 1 steel. The growth rate of short cracks is faster than those of long ones around the threshold stress intensity. The thresh- old stress intensity for short crack growth decreases with decreasing crack length. The acceleration effect of the salt water, as compared with atmosphere environ- ment, on the growth of short cracks under fatigue is much greater than that on the growth of long cracks.
