3004铝合金铸轧法生产罐材中间退火的ODF分析

ODF Analysis of Middle Annealing of 3004 Aluminum Alloy Sheet for Can -Making Made by Melt-Rolling Process

对３００４铝合金铸轧法生产罐材中间退火状态的织构进行了ＯＤＦ（ＳｐａｃｅＯｒｉｅｎｔａｔｉｏｎＤｉｓｔｒｉ－ｂｕｔｉｏｎＦｕｎｃｔｉｏｎ）分析，结果表明该合金回复状态产生的｛１００｝〈００１〉依靠取向成核产生强织构；在再结晶状态产生的｛１００｝〈００１〉依靠取向长大产生强织构；回复处理保留了轧制织构，再结晶处理使这些轧制织构晶粒绕晶面法线和晶向产生转动。

By using the space orientation distribution function, the textures of 3004 aluminumalloysheet for can-making made by melt-rolling process were analysed. The results show that {100} <001>texture was produced in the alloy after recovery annealing and it relies on orientation nucleation ; {100}<001> texture was produced in the alloy after recrystallization and it relies on orientation growth. After recovery annealing, the rolling textures were maintained ;after recrystallization annealing, the grains of the rolling textures were turned round normal direction of crystal face and crystal orientation.
