摘要:
The distributions of grain boundaries in hot-strained 80 wt% Ni-20 wt% Cr alloy have been determined with respect to their misorientation angles and the crystallographic axes, as well as to the reciprocal density σ of coincidence sites. It is established that the grain-boundary distribution in the alloy formed under high-temperature deformation differs from the stable grain-boundary spectrum typical of statically recrystallized materials that are prone to annealing twinning. There are also differences in the deformation behaviour of the samples with different spectra of grain boundaries. It is demonstrated that, in principle, it is possible to control the material properties through the grain-boundary distribution.
