In the fabrication of heat treatable aluminum parts for the aeronautic industry, quenching is a key step to obtain the required mechanical characteristics after aging. For thick plates, thermal gradients cause non-homogeneous plastic strain resulting in re ...

The influence of microchemistry on the softening behaviour of two cold-rolled Al–Mn–Fe–Si alloys with different initial amounts of Mn (0.4 and 1.0 wt%) is studied. In addition to their as-cast conditions, the supersaturated Al–Mn–Fe-Si alloys were appropri ...
Five different grain sizes are produced in 0.17 wt% carbon steel using varying rates of cooling from austenitization temperatures. Controlled furnace cooling from 1100 °C and 950 °C produces coarse ferrite grains of 40 µm and 32 µm diameter, respectively, ...
The influence of microchemistry on the softening behaviour of two cold-rolled Al-Mn-Fe-Si alloys with different initial amounts of Mn (0.4 and 1.0. wt%) is studied. In addition to their as-cast conditions, the supersaturated Al-Mn-Fe-Si alloys were appropr ...
Nanoindentation tests were carried out on the surface of polymer nanocomposites exhibiting either graded or homogeneous distributions of Fe3O4@silica core-shell nanoparticles in a photocurable polymeric matrix. The results reveal a complex interplay betwee ...
In this paper, a simple but realistic approach is presented to predict the as-quenched residual stress distribution in thick 7xxx aluminium alloy plates. Instead of modelling precipitation that occurs during quenching, a thermo-mechanical model is used who ...
Investigation of the microstructural evolution of Al-Mn-Fe-Si alloys during annealing after cold rolling has been carried out. The effect of microchemistry state in terms of Mn in solid solution, constituents, size and volume fraction of dispersoids, intro ...
We explore the influence of the metal microstructure on the compressive flow stress of replicated microcellular 400-mu m pore size Al-4.5 wt%Cu solidified at two different solidification cooling rates, in the as-cast and T6 conditions. It is found that the ...
The recrystallization textures of a cold-rolled Al-Mn-Fe-Si model alloy with three different microchemistry states after non-isothermal annealing were studied. The microstructure and texture evolution have been characterized by EBSD. It is clearly demonstr ...
Grain boundaries (GBs) play an important role for the mechanical properties of metals. In addition to dislocation motion inside the grains, some metal alloys deform along the GBs at high temperatures. GBs can also be the cause of a brittle behaviour of som ...
