Keywords： fractal dimension , null , null , null

By means of fractal analysis,the fractal dimension with relation to the impact toughness,im- pact fracture characteristics and mierostructures of steel under low temperature impact have been investigated.Experimental results show that the logarithms of impact toughness in- creases monotonically with the increase of fractal dimension.The microstruetures have a great influence on fraetal dimension.There is an appropriate correlation between fraetal dimension and fracture mechanism.
