Abstract

This article describes the changes in order and texture of a 73 pct cold-rolled Ni3Al(B, Zr) alloy after it is subjected to recrystallization annealing. In the initial stages of annealing, the deformed starting material undergoes both recovery and reordering. This is followed by recrystallization with continued annealing. The cold-rolled material, which has a DO22 structure, undergoes a change in order during the recovery stage, leading to the formation of the earlier L12 structure. This is accompanied by a drastic decrease in the texture severity. The weak texture at the end of the recovery/reordering stage persists even during recrystallization, and this finally leads to the formation of a weak texture.
