The shapes and orientations of precipitates have important influences on the mechanical properties precipitation-strengthened magnesium alloys. In this work, microstructure precipitation behaviors an aged Mg-3.0 wt % La alloy are investigated by atomic resolution scanning transmission electron microscopy. main precipitate product at peak-aged stage is a category La-enriched solid solution with face-centered cubic (FCC) lattice, which will subsequently evolve into another strengthening phase...
Different gel processes were devised to synthesize Bi2Sr2CaCu2O8+δ (Bi2212)powders by sol–gel method. The phase purity, grain size and crystallinity of Bi2212 powders dramatically improved a modified method called Pechini. Meanwhile, the sintering time was correspondingly reduced half. According investigations different mechanism on quality powders, polymerization increased stability network which inhibited some complexes segregated from before auto-combustion. Furthermore, esterification...
The morphology and dimension of W phases play an important role in determining mechanical properties Mg−RE−Zn (where RE denotes rare earth elements) alloys. In this study, the γ′ platelet particle occurred aged Mg−2Dy–0.5Zn (at.%) alloys were investigated by aberration-corrected scanning transmission electron microscopy. A novel formation mechanism phase was proposed, its effects on particle, as well alloys, also discussed particularly. Different from other nucleation growth Mg−Dy–Zn mainly...
It is a long-debated issue whether or not β′′ forms in magnesium-rare earth alloys. In this study, after solid solution and aging treatment, the binary Mg-3.0 wt% La alloys were characterized using atomic-resolution scanning transmission electron microscopy. A large number of metastable precipitate was captured successfully along [0001]α 112¯0α directions. The observation reveals that inchoate composed single row linked hexagonal rings. Under further aging, expansion direction ring limited...
The structural evolution from β1 (Mg3Ce) to β (Mg12Ce) precipitates, which takes place at the over-aged stage of binary Mg−Ce alloys, are investigated by high-angle annular dark-field scanning transmission electron microscopy. transformation mainly occurs in {111}β1 crystallographic planes, where newly formed lattices exhibit two categories domain structures, namely rotational and translational domains. is composed three domains (βRA, βRB βRC), related a 120° rotation with respect each other...
