| 摘 要： | 应用小角X射线散射技术研究二元Al-Li(Li的质量分数为2.70%)合金时效-回归-再时效析出δ′相的行为.发现再时效8h析出的δ′相与基体之间存在明显的过渡界面层,再时效16h以后过渡界面层消失.表明δ′相粒子的长大首先是吞噬过渡界面层长大,然后是互相吞并长大.关键词：Al-Li合金时效－回归－再时效过渡界面层

| Abstract: | Small-angle X-ray scattering has been used to study the precipitation behavior of the δ′ phase in an Al-2.70mass%Li alloy treated by aging-retrogression-reaging. The results show that a transitional interfacial layer exists between the δ′ phase and the matrix in 8h reaging, but the transitional interfacial layer disappears in 16h reaging. This suggests that the δ′ phase particles are coarsened by “licking up” the transition interfacial layer before 16h reaging and swallow up each other after 16h reaging. |
