摘 要: 研究了Fe-16Al(摩爾分數(shù)， %， 下同)基合金與Fe-28Al基合金的溫軋形變與再結(jié)晶織構(gòu)。 結(jié)果表明， Fe-Al合金系中， 不同Al含量對塑性變形及再結(jié)晶機制的影響是與由Al含量不同引起的結(jié)構(gòu)變化密切相聯(lián)系的。 Fe-16基合金形變與再結(jié)晶行為與純BCC金屬類似。 Fe-28Al基合金變形時外力對織構(gòu)形成有敏感影響,變形時晶界的應(yīng)變協(xié)調(diào)能力較弱。 且再結(jié)晶后晶粒取向分布有明顯的隨機化傾向。

Abstract:Deformation texture during warm rolling and recrystallization texture of alloys based on Fe-16Al and Fe-28Al were investigated. It has been shown that the influence of different content of aluminium on the mechanism in plastic deformation and recrystallization is closely related to the crystal structure. Deformation and recrystallization behaviour of Fe-16Al-based alloy is similar to that of conventional non-ordered b.c.c. metals. In plastic deformation of Fe-28Al-based alloy the texture development is sensitive to applied stress, it seems that the compatibility with shear strain of boundary of Fe3Al based alloy is weak, and the grain orientation distribution after recrystallization were randomly oriented.
