电场退火对冷轧工业纯锌板再结晶织构的影响

借助于X射线衍射的三维取向分布函数(ODF)研究了电场退火对70%,80%和90%冷轧变形量的工业纯锌板在160℃分别保温1,3,5,10,15,30min条件下再结晶织构的影响.ODF分析结果表明:电场并没有改变工业纯锌板退火过程中再结晶织构的形成机制,而电场显著提高了3种冷轧压下量工业纯锌板退火样品再结晶织构的强度.电场明显促进了冷轧{1 0 1 8}面织构向再结晶{1 0 1 3}〈1 0 1 1〉板织构的演变,其中以70%冷轧变形量样品最为明显.

Effects of Electric Field Annealing on Recrystallization Textures of Pure Zinc Sheets

The effects of electric field annealing on the recrystallization textures of commercially pure zinc sheets were studied by means of 3-D ODF (orientation distribution functions) analysis, where the sheets were cold rolled separately with 70%, 80% and 90% reduction and each of them was hold at 160°C for 1, 3, 5, 10, 15 and 30 min. The results showed that the electric field does not change the mechanism of formation and development of their recrystallization textures in annealing process, but increases obviously the recrystallization texture intensities of the sample sheets rolled with 3 different reduction and isothermally annealed, i.e., the electric field can promote the evolution from {1¯018}-plane texture to {1¯013}<101¯1> texture and, among those sample sheets, the 70% cold reduced sheet is the most evident one.
