【摘要】：以1235鑄軋板(7.0 mm)經(jīng)過兩道次冷軋后的1.1 mm厚的冷軋坯料為對(duì)象,借助光學(xué)顯微鏡(OM)、掃描電子顯微鏡(SEM)及能譜分析儀(EDS)、定量金相分析技術(shù)和電解拋光等試驗(yàn)手段,研究了退火溫度對(duì)1.1 mm厚的1235鋁箔坯料組織的影響。結(jié)果表明:在相同的退火時(shí)間(6 h)內(nèi),隨退火溫度(320~420℃)升高,析出相(Al Fe Si)數(shù)量先增加而后減少且粗化;退火溫度為380℃時(shí),析出相數(shù)量多且均勻細(xì)小,平均尺寸約為3μm。再結(jié)晶溫度的區(qū)間為320~340℃;隨著退火溫度升高,再結(jié)晶晶粒逐漸長(zhǎng)大;退火溫度為380℃時(shí),再結(jié)晶晶粒數(shù)量多且均勻細(xì)小,平均尺寸約為23μm。因此,在380℃保溫6 h的退火工藝最佳。
[Abstract]:The 1. 1 mm thick cold rolled blank of 1235 cast and rolled sheet (7. 0 mm) after two cold rolling passes was taken as an object. (OM), scanning electron microscope (SEM) and energy dispersive analyzer (EDS),) were used for scanning electron microscope (SEM) and energy spectrum analyzer (EDS),). The effect of annealing temperature on the microstructure of 1235 aluminum foil blank with 1. 1 mm thickness was studied by quantitative metallographic analysis and electrolytic polishing. The results show that in the same annealing time (6 h), with the increase of annealing temperature (320,420 鈩，
