Developments of high-strength aluminum alloys have always faced a difficult problem: owing to their small size, the early-stage strengthening precipitates are difficult to characterize in terms of composition, structure and evolution.Here we employ atomic-resolution transmission electron microscopy (TEM) imaging and first-principles energy calculations to address these problems.Recent years, we have investigated tens of typical high strength aluminum alloys, such as 2xxx (AlCu, AlCuMg and AlCuLiMg), 6xxx (AlMgSi and AlMgSiCu) and 7xxx (AlZnMg and AlZnMgCu) alloys, with different compositions and with varying thermal processes for understanding their property-structure-process correlations.

Metastable precipitates in 2xxx and 6xxx alloys are needles or elongated plates (laths) along ＜001＞Al directions, locked to the Al periodicity (4.05 (A)).They are effectively bundles of (ideally) pure
Al-Mg alloy is widely known as a typical class-Ⅰ or class-A type solid solution.High-temperature deformation in this alloy has been reported to be rate-controlled by solute drag creep.The solute drag
In order to investigate the effect of cold-rolling and aging on precipitation and recrystallization behavior of Al-Er-Zr alloy, two thermo-mechanical processes containing peak aging+cold-rolling (A+CR
The casting table with lubricating oil and wipe was used in this study, 30T 7055 superhigh strength aluminium alloy with diameter of 582 mm were cast successfully, and the effects of parameters on mel
A horizontal-type twin roll casting method has been popular for producing aluminum alloy strips, however, it is characterized by a relatively low productivity (1～6 m/min).In contrast, a vertical-type
Al-11.5 wt.％Si alloy was modified by Sr and then solidified in different moulds.The results showed that whether or not adding Sr modification agent the electrical conductivities of alloys solidified i
In this work, a series of Al-Al4C3, Mg-Al4C3 and Al-Mg-Al4C3 master alloys were developed for refining α-Mg grains and their nucleating mechanism were also investigated.The master alloys exhibit a rem
The microstructure of Al-F.e binary ahoy processed by metal mould casting was investigated.The effects produced by Fe contents and the pouring temperature on the solidification structures of Al-Fe bin
During casting the semi-solid microstructure is frequently subjected to the tensile stresses, which are closely related to cast defects such as hot tearing, porosity and macrosegregation.To examine th
A low frequency electromagnetic field was introduced into the direct chill (DC) casting process and the ingots of Al-Cu alloy were prepared to study the macrosegregation behaviour of the ingots under
