Semi-Planetary Rolling and Changes of Fine Structure and Microstructure
Résumé
The strain intensity in the proximity of planetary cylinder, in the case of semi-planetary rolling is greater than in the proximity of the massive cylinder. This fact leads at the variation of the microstructure and fine structure characteristics: the mosaic block dimension, second order stresses, dislocations density, micro-hardness into the thickness of rolled body. In the paper it presents the research results for identify and evaluate the structure modifications at the semi-planetary rolling.
