摘要：
Periodic and random surface roughness of cyclically loaded specimens was under investigation. Specimens of ferritic and austenitic steels were measured using new optical method based on laser light scattering on rough surfaces. Measured dependencies of autocorrelation length of surface T on relative number of cycles N/N-f indicate an onset of a stable extrusion/intrusion relief on the specimen surface caused by fatigue process.
