Potential for obtaining an ultrafine microstructure of low-carbon steel using accumulative roll bonding

Popis výsledku v původním jazyce

The objective of the present work was to trial the ARB method on commercially available steels at the company COMTES FHT. Consequently, a steel with 0.011 wt. % carbon was chosen. The specimens were prepared with great care, involving mainly their surface and the quality of bonding in order to successfully achieve 50 percent reduction in height in a single pass at elevated temperature. Protection of specimens against scale formation proved very important during heating to the testing temperature in the500-600 °C interval. Due to the complexity of the ARB method, only two bonding cycles were completed. The initial mean grain size of the annealed feedstock was 18 ?7 ?m. After the first ARB cycle, grains with a length of 24 ?10 ?m and a width of 8 ?3 ?mwere found. The ultrafine-grained surface layer had a thickness of approximately 150 ? 200 ?m. After the second ARB cycle, the microstructure of this type was found in the centre of the specimens. The strength after two passes reached 660
