Evolution of the grain-boundary misorientation spectrum in recrystallized nichrome

The mechanisms of the formation of grain-boundary misorientation spectra (G BMS) in materials with moderate stacking-fault energies were considered by the example of nichrome. These mechanisms are multiple twinning and grain-b oundary splitting. It is shown that if the former mechanism is dominating, the fraction of the Sigma 3 boundaries in the spectra formed does not excee d 40%, whereas the domination of the latter mechanism results in spectra wi th about 70% Sigma 3 boundaries. The data on the evolution of the grain-bou ndary misorientation spectra are used to analyze the type of recrystallizat ion in submicrocrystalline nichrome.
