Abstract Scope |
In the present study, Cu-Fe-P specimens were subjected to the 20%, 40%, 60%, and 80% reduction ratio (RR) through cryogenic rolling (CR). High-resolution EBSD was used to characterize the microstructural evolution in CR specimens. Severely deformed CR specimens showed the formation of strain localizations (SLs), which were predominantly formed in the Copper-type grains. Self-annealing phenomena was observed in the severely deformed CR specimens which causes the grain nucleation at the deformed GBs and at the SLs. Nucleation of new grains confirms the activation of discontinuous SRX (DSRX) and continuous SRX (CSRX) in CR Cu-Fe-P alloy specimens. Initial Cu-Fe-P specimen showed weak plane strain texture whose intensity goes on increase with the increase in RR. SRX at SLs shows the preferential formation of Copper, Brass, and S nucleated grains in the CR-80 specimen. Time-dependent decay in the hardness values for the CR specimens, attributing to the SRV and SRX. |
