Recrystallization Textures in Heavily Cold-Rolled Ni₃Al Based Single Crystals

Abstract:

Texture evolution during recrystallization and grain growth was examined for a Ni3Al/Ni two-phase single crystal (binary Ni-18 at.% Al) 83% cold-rolled, then compared with that for a Ni3Al single-phase single crystal (Ni-24 at.% Al). The cold-rolled single crystal had a sharp {110}<001> (Goss) texture. When it was recrystallized at 873K, the texture changed into a complicated one consisting of several components. Most of them had a special rotation relationship to the original Goss texture, i.e. 40˚ about <111>, which special relationship was similarly observed in the single-phase case. The 40˚<111> texture became shaper with no quantitative change as the grain growth proceeded. This high stability of the recrystallized texture contrasted with the single-phase case in which the authors previously found that the texture returned to the original Goss texture. The difference was discussed based on the orientation analysis by an electron backscattered diffraction method.
