摘要 RPV模拟钢样品经过890℃水淬,660℃调质处理,然后在400℃时效13000h后,用高分辨透射电镜和能谱仪相结合的方法研究了RPV模拟钢中纳米富Cu析出相中的复杂晶体结构.纳米富Cu析出相的平均尺寸约为20nm,除了观察到常见的亚稳态9R结构、3R结构和稳态fcc结构外,还观察到同一富Cu析出相由3种不同的晶体结构组成,并分别分布在5个不同的区域中,包括1处9R、2处fcc 和2处3R 结构.9R结构与相邻的2个fcc结构形成的界面都具有特定的晶体取向,呈半共格关系,是由非孪晶9R结构演化而来.2处3R结构互为孪晶关系,是由孪晶9R结构演化而来.这种状态反映了纳米富Cu析出相从亚稳态演化到稳态结构的复杂过程.

Abstract:The specimens of the reactor pressure vessel (RPV) model steels were tempered at 660℃ after water quenching from 890℃, aging treatment was then conducted at 400℃ for 13000h. The Cu-rich precipitates were characterized by high resolution transmission electron microscopy (HRTEM) and energy dispersive spectroscopy (EDS) in order to study the transition process from metastable to stable structure. The average size of the nano Cu-rich precipitates is about 20nm, besides the metastable 9R,3R and the stable fcc crystal structures, it is observed that three different crystal structures distributed in five different regions existing in the same nano Cu-rich precipitate, including one 9R, two of fcc and two of 3R crystal structures. The boundaries formed by 9R structure with its two adjacent fcc structures have specific crystal orientations, their interfaces are semi-coherent. They are evolved from non-twin 9R structure. The two 3R structures are twins, and evolved from twin 9R structure. The above phenomena reflect the complex processes from metastable to stable structure.
Key wordsreactor pressure vessel model steel    thermal aging    nano Cu-rich precipitate    9R crystal structure
