摘要:
本文介绍了研究铝合金析出强化过程中微结构演变的几种先进手段,包括高角环形暗场-扫描透射电子显微术,三维原子探针技术,选区电子衍射模拟和第一性原理计算;综述了作者及国内外学者使用这些手段研究Cu对6000系和7000系铝合金时效过程中微结构影响的新进展;最后展望了通过对铝合金微结构的定量模拟结合实验验证进行合金设计的发展方向。
Abstract:
The advantages of several advanced methods in characterizing the microstructural evolution during ageing precipitation of Al alloys, including high-angle annular dark field -scanning transmission electron microscopy, 3-dimensional atom probe, selected area electron diffraction simulation and first principle calculations, have been introduced. The progress in investigating the effects of Cu addition on the microstructural evolution during ageing precipitation of 6000 and 7000 Al alloys with these methods is briefly reviewed. The advancing of these techniques and the progress in microstructural investigations promise a bright future of alloy design by combining quantitative simulation on microstructure of Al alloys with key experimental verifications.
