轧制压下量对Fe-8Al合金板材耐蚀性的影响
Effect of Rolling Reduction on the Corrosion Resistance of Fe-8Al Alloy Sheets
摘 要
采用真空电磁感应熔炼制备了Fe-8Al合金，采用80%、70%、63%和50%轧制压下量制成合金板材，最后对4种Fe-8Al合金板材进行900 ℃退火保温10 min后水冷的热处理。采用扫描电子显微镜（SEM），拉伸试验和电化学试验对4种Fe-8Al合金板材的性能进行分析。结果表明：随着轧制压下量的增大，Fe-8Al合金板的晶粒尺寸逐渐减小；轧制压下量为80%时Fe-8Al合金板材的综合力学性能最好；轧制压下量为63%时Fe-8Al合金在5%（质量分数）Na2SO4溶液中的耐蚀性最好。80%为Fe-8Al合金轧制工艺制度的最佳轧制压下量。

Abstract
Fe-8Al alloy was prepared by vacuum induction melting. The alloy sheets were prepared by 70%, 63%, 50% and 80% rolling reduction, respectively, then the Fe-8Al alloy were treated at 900 ℃ for 10 minutes and water-cooled. SEM, tensile test and electrochemical test were used to investigate the properties of 4 Fe-8Al alloy sheets. The results showed that with the increase of rolling reduction, the material grain size decreased. Fe-Al alloy sample with a rolling reduction of 80% had the best comprehensive mechanical properties. Fe-Al alloy sample with a rolling reduction of 63% had the best corrosion resistance in 5% (mass) Na2SO4 solution. The best rolling reduction for Fe-8Al alloy was 80%.
