Effects of preferred grain orientation on the on lüders bands appearance

In this paper, the influence of preferential grain orientation was examined. Parallel tests were conducted on the samples from the same steel strip, taken in the direction and perpendicular to the direction of rolling the strip. Steel strip has a homogeneous fine- grained ferrite-pearlite microstructure. Using the methods of thermography it has been found that at the beginning of the plastic flow Lüders bands occur, pointing to the fact that the preferential grain orientation, in the case of steel with the fine-grained ferrite-pearlite microstructure, has no effect on the appearance of the Lüders bands.
