Effect of thermal fatigue cracks on brittle-ductile deformation and failure of cbcm roller surface layers

  • Published:
Metallurgist Aims and scope

The effect of multiple cracking for steel 25Kh1MF on its deformation behavior is analyzed. Fractal theory is used to develop new methods of digital diagnosis of deformation in material with multiple defects. It is established that the fractal dimension of multiple cracking increases uniformly with an increase in cracking damage area. Physical features of these principles are analyzed.
