Recycling of stainless steel bar scrap by radial-shear rolling to obtain an ultrafine-grained gradient structure

This work is devoted to the study of possibility recycling bar scrap stainless metals using radial-shear rolling. In course studies on deformation in form pins made 12X18N9T austenitic steel a rolling mill, resulting was obtained microstructure two different types: periphery an equiaxed ultrafine-grained structure with grain size 0.4–0.6 microns formed; axial zone anoriented, banded texture obtained. discrepancy peripheral and zones, together results cross-section microhardness measurements samples total degree 44.4 %, indicates gradient nature microstructure.
