Paper Title:
XRD Investigation of Impact Pattern on Ball Bearing Steel Samples
  Abstract

The main purpose of this work is to reveal the structural changes occured after the impact test on ball bearing steel samples, relative to their ferrite-pearlite phase. The XRD analysis has been used to investigate the level of first and second order internal stresses, the dimensions of mosaic blocks as well as the dislocation density in crystal lattice. The influence of the impact velocity, material hardness and surface roughness on fine structural parameters, mentioned above, is also analysed. On the basis of structural changes it is possible to control the material response during the impact loading.
