Abstract
Thin nickel sheets were fabricated by electroforming, and cold rolled to improve their strength. The thin nickel sheets have very fine grains with a {001}<uv0> fiber texture. Cold rolling results in evolving a {001}<110> orientation and the formation of a weak {111}<uvw> fiber component. Micro-hardness of the nickel sheet on the surface normal to the normal direction (ND) was increased from 247.8 to 354.4 Hv by cold rolling with 87.5% reduction. The corrosion potential and corrosion rate of the nickel sheet in artificial sea water were in the ranges of −27 to −12 mVSCE and 4.2 × 10−7–1.8 × 10−6 A cm−2, respectively. The change in corrosion behavior with cold rolling on the surface normal to ND has little relation to crystallographic texture because of a stable {001} texture during rolling, unlike nickel bulk samples.
