采用氨基磺酸盐电解液电沉积制备了具有纳米晶粒的镍箔。电解质的pH在2.8至5.1的范围内变化。微晶尺寸在pH = 4.8附近显示出最小值。随着晶粒尺寸的减小，强度和应变硬化速率增加，（100）织构变得不那么明显。本文讨论了室温和-196 ℃拉伸试验中位错的产生和运动。(C)1999《冶金学报》
Nickel foils with nano-size grains were produced by electrodeposition using a sulfamate-based electrolyte. The pH of the electrolyte was varied within the 2.8 to 5.1 range. The crystallite size showed a minimum around pH = 4.8. As grain size was reduced, the strength and strain hardening rate increased and the (100) texture became less prominent. In this paper results of tensile testing at room temperature and -196 degrees C are discussed in terms of dislocation generation and motion. (C) 1999 Acta Metallurgica Inc.
