    摘要:

    鋯合金β相冷卻組織對于發(fā)展高性能燃料包殼具有至關(guān)重要的作用。本工作從冷卻速率和雜質(zhì)元素兩個影響因素出發(fā)，對核反應(yīng)堆用鋯合金β → α轉(zhuǎn)變組織的相關(guān)研究進(jìn)行了綜述。鋯合金的馬氏體轉(zhuǎn)變?yōu)闊o擴(kuò)散的切變過程，不產(chǎn)生表面浮凸，Ms不隨冷卻速率變化。成分相同時，隨著β冷卻速率的增加，鋯合金微觀結(jié)構(gòu)按如下次序變化：Lenticular組織→Parallel-plate魏氏組織→Basketweave魏氏組織→馬氏體。相同冷卻速率下，當(dāng)雜質(zhì)元素參與形成難溶的第二相時，會促進(jìn)Basketweave組織的形成，而當(dāng)這些元素提高β轉(zhuǎn)變溫度時，則傾向于促進(jìn)Parallel-plate組織的形成

    Abstract:

    This paper presents a comprehensive review about the effect of cooling rates and impurities on the microstructure of zirconium alloys during β→α transformation with the expectation to facilitate the development of high-performance zirconium-based cladding materials. For zirconium alloys, the diffusionless Martensitic transformation does not produce a surface rumpling after quenching the pre-polished specimens. The Ms temperature keeps independent of β quenching rates. When alloy composition is fixed, increasing of cooling rate causes microstructural change in the following sequence: lenticular α→Parallel plate α→Basketweave α→Martensitic α'. The impurities which can form insoluble second phase particles in β phase will promote the formation of Basketweave Widmanstatten structures. However, the impurities that might increase β phase transformation temperature will lead to more Parallel-plate Widmanstatten structures
