Résumé / Abstract

Scanning electron microscopy and electron backscattered patterns, EBSP, have been employed to reveal both the grain structure and texture of 90% cold-rolled polycrystalline nickel after 1-hour anneals at a variety of temperatures. After annealing at either 400° or 500°C, small, cube-oriented, equi-axed grains were produced via primary recrystallization. At 600°C, large {124}<211> oriented grains accounted for an increasing proportion of the microstructure, until at 1000°C only large grains (∼600 μm) and a sharp {124}<211> texture were present. Detailed EBSP analyses of the grain boundaries surrounding the large abnormally grown grains observed at 600°C demonstrated that formation of the secondary recrystallization texture was due to migration of high-mobility, random high-angle boundaries around grains that had a size advantage, consistent with the Abbruzzese-Lücke model.
