B′ is a common type of metastable precipitate in over-aged Al-Mg-Si alloys, which long regarded as variation the Q Al-Mg-Si-Cu alloys due to similarity between their lattice parameters. Atomic-resolution high angle annular dark field scanning transmission electron microscopy and energy dispersive X-ray elemental mapping at low beam damage conditions, well first-principles calculations were used explore atomistic structure B′. It has hexagonal unit cell with space group P6¯ parameters a=...
It is well known that lower quench rate leads to the formation of precipitate free zones (PFZs) adjacent grain boundaries in aging hardening materials such as Al–Mg–Si alloys. However, combined effect PFZs and intragranular precipitates on yield strength alloys not systematically understood. To clarify this, an alloy was water/oil/air quenched after solid solution treatment, then aged at 180 °C for 6 h. found a led coarser wider PFZs. The effects were separated by quantitative...
Protein-ligand binding affinity plays an important role in drug discovery, especially during virtual screening and hit-to-lead optimization. Computational chemistry machine learning methods have been developed to investigate these tasks. Despite the encouraging performance, optimization are often studied separately by existing methods, partially because they performed sequentially discovery pipeline, thereby overlooking their interdependency complementarity. To address this problem, we...
The microstructure, texture, and mechanical properties of as-extruded cold-rolled Mg–8Li–3Al–2Zn-1Gd-0.2Zr (LAZ832-1Gd-0.2Zr) alloys were investigated with the aim strengthening alloy by combining hot extrusion cold rolling. Cold rolling does not change phase composition LAZ832-1Gd-0.2Zr alloy, but introduces a larger number dislocations twins into matrix. leads to weakening original {0001} basal {112‾0}-{011‾0} prismatic textures in α-Mg matrix, as well α γ fiber β-Li But new slip systems...
β-AlFeSi is one of the most common and damaging intermetallics in aluminum alloys containing silicon. The study its growth behavior crucial for alloy design. In this work, Al-8.1Si–5Fe Al–13Si–3Fe were cast to β-AlFeSi. skirt like clusters formed by splitting discovered, phenomenon was found be mainly caused thermal stress. By micro atomic scale electron microscopy studies, a layer-by-layer mode along (001) crystal plane proposed addition, it that grows heat flow, preferred orientation...
Precipitate free zones (PFZs) near grain boundaries generally soften alloys. The quenching rate after solution treatment is an important factor influencing the width of PFZs in Al-Mg-Si-Cu alloy. This study explored effects high rates on boundary microstructures and mechanical properties Samples various thickness were quenched water at room temperature ethylene glycol -40 °C, respectively. results showed that rapidly samples °C exhibited better comprehensive than water-quenched samples....
We demonstrate a simple optical fiber microfluidic control device based on photothermal effect induced convection, which can realize flexible manipulation and particle sorting over range of hundreds microns. Three single-mode fibers in regular arrangement were utilized for the realization capture function, simplifies complex equipment reduces cost traditional tweezers. also display unique mode: horizontal particles by moving vertically. It will hopefully be applied biomedical, chemical...
Abstract This work attempts to quantitatively describe the microstructural evolution in a new commercial 6 ××× aluminum alloy developed an industrial laboratory (Al-0.87Si-0.81Mg-0.51Zn-0.46Cu-0.19Fe-0.09Mn, wt.%), during solidification by using phase-field simulation supported experimental measurements.
