  • Influence of sample direction on the impact toughness of the API-X42 microalloyed steel with a banded structure = Vpliv usmerjenosti vzorcev na udarno žilavost mikrolegiranega jekla API-X42 s trakavo mikrostrukturo
    Salimi, Ahmadreza ...
    The layering of a microstructure parallel to the direction of the material flow during the hot working process is called banding. In the present paper, the severity of ferrite-pearlite banding in the ... API-X42 microalloyed steel and its effects on the impact energy are studied. Specifically, the impact toughness is examined in the cases of banded and non-banded samples along two directions, perpendicular and parallel to the rolling, and the obtained results are compared. Metallographic examinations, together with the Charpy impact tests at 0 °C and -18 °C, were done for both directions, parallel and perpendicular to the rolling. The results showed a dependence of the impact energy on the sample direction relative to the rolling to be larger with the banded than the non-banded sample. The difference between the impact energies for the directions parallel and perpendicular to the rolling was also noticed to be caused by the increasing anisotropy index.
