초록

Micro structure observation for low carbon steel base material and heat treatment(annealing),performing a tensile test and impact test, the specimen after the impact test is intended to evaluate thecrack propagation characteristics by performing a fractal dimension analysis. The tensile strength of thebase materials were observed higher compared to the heat treated materials, impact absorbed energy ofheat treated materials was a higher than base materials. Impact Test and fractal dimension of the sideof the test specimen was shown significantly more test temperature increases, heat treated material washigher than the base material.
