摘 要: 利用X射線衍射的三維取向分布函數(shù),研究工業(yè)純鋅板在160 ℃時電場與非電場退火保溫不同時間條件下的再結(jié)晶織構(gòu)的形成與演變,同時進行顯微硬度測試。結(jié)果表明:電場退火推遲軋制工業(yè)純鋅板再結(jié)晶進程,從而導(dǎo)致電場退火樣品的顯微硬度值均高于非電場退火樣品的顯微硬度值。電場顯著提高退火后樣品的再結(jié)晶織構(gòu)強度,即電場明顯促進冷軋{1018}面織構(gòu)向再結(jié)晶{1013}<1011>板織構(gòu)的演變,而且這種影響在再結(jié)晶晶粒的長大階段表現(xiàn)得尤為突出。電場并沒有改變工業(yè)純鋅板退火過程中再結(jié)晶織構(gòu)的形成機制。

Abstract:Abstract: The effects of electric field on recrystallization texture evolution and microhardness in a pure zinc sheet during annealing at 160 ℃ for different times were studied by means of X-ray diffraction techniques. The microhardness was measured. The results show that the electric field retards the recrystallization process and decreases the microhardness of pure zinc sheet during annealing. The electric field annealing does not change the evolution mechanism of recrystallization texture in the pure zinc sheet, but strengthens the intensity of recrystallization texture,i.e. electric field annealing improves the evolution from cold rolled {1018} texture component to recrystallization {1013}<1011> texture component, especially at the stage of grain growth
Key words: pure zinc sheet; electric field annealing; recrystallization texture; ODF; hardness
