Abstract

Abstract: Microstructure and texture of the rolled plane(RD-TD) and cut plane(RD-ND) of 30% cold-rolled N18 alloy annealed at 530 ℃ for different time were characterized and analyzed by means of EBSD. For RD-TD plane, the initial grain orientation is <0001>//ND, the orientations of recrystallized grains are <0001>//ND and <1210>//RD texture. For the RD-ND plane, the initial grain orientation is mainly <1010>// RD and <1210>//RD. After recrystallization annealing, three different orientations of<1010>//ND, <1210>//ND and <0001> tilted to TD pole ±85° are formed. The grain size on the RD-TD plane is larger than that on the RD-ND plane, which provides theoretical support for the reprocessing of Zr alloy.

Key words: N18 alloy, recrystallization, texture evolution
