摘要:

利用TEM对Al-6Mg-0.7Mn-0.1Zr-0.3Er合金在退火过程中Al₃(Zr_xEr_1-x)的析出和生
长行为进行了研究. 结果表明: 低温退火(280℃, 470℃)和高温短时间退火(510℃, t≦100 h)
时, Al₃(Zr_xEr_1-x)析出相的粗化符合LSW理论(n=1/3), 高温长时间退火(510℃, 300 h, 500 h)时,
Al₃(Zr_xEr_1-x)析出相没有进一步粗化; Al₃(Zr_xEr_1-x)析出相的粗化主要受Er, Zr等溶质原子在
$\alpha$-Al基体中的扩散影响. 二次析出相Al₃(Zr_xEr_1-x)在较低温度(280和470℃)退火时均匀
分布于α-Al基体中, 较高温度(510℃)退火则呈线状不均匀分布. 在同一退火温度下, 随着
退火过程的进行, Al₃(Zr_xEr_1-x)析出相的形貌逐渐从四方体向规则的球体过渡, 析出相
Al₃(Zr_xEr_1-x)中的x增大.

关键词 ：退火, Al$_{3}$(Zr$_{x}$Er$_{1-x}$), 粗化

Abstract：

Erbium (Er) has attracted considerable attention as a substitute to scandium (Sc) for microalloying. The solid solution of Er and Zr decomposes to form a dispersion of secondary Al₃(Zr_xEr_1-x) during annealing. This secondary Al₃(Zr_xEr_1-x) precipitates improve strength, especially the elevated temperature strength. In the present paper we investigate the evolution of Al₃(Zr_xEr_1-x) precipitate during annealing by transmission electron microscopy (TEM). The Al₃(Zr_xEr_1-x) precipitates nucleate homogeneously at lower temperatures (280℃ and 470 ℃). The transition from homogeneous to heterogeneous nucleation at higher aging temperature (510℃) is a natural consequence of the reduced driving force for nucleus formation as the temperature increases and the Er supersaturation in the α-Al matrix decreases. The change in morphology of the Al₃(Zr_xEr_1-x) precipitates from faceted to approximately spheroidal is associated with a change in the value of interfacial free energies. The diameter and the ratio of Zr/Er increase with increasing aging time at constant temperature. The coarsening of Al₃(Zr_xEr_1-x) is dependent on the diffusivity of Er, Zr in α-Al.

Key words： annealing Al₃(Zr_xEr_1-x) coarsening
