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 ...
The softening behaviour during non-isothermal annealing of a cold-rolled Al–Mn–Fe–Si model alloy was studied as a function of the state of microchemistry, in terms of the solute level of Mn, size and spatial distribution of the Mn-bearing dispersoids, as w ...
W-2Y, W-1Y(2)O(3) and W-2Y(2)O(3) materials have been fabricated using two different powder metallurgy methods. While W-2Y and W-1Y(2)O(3) have been fabricated using mechanical alloying and hot isostatic pressing (Hipping), W-2Y(2)O(3) has been fabricated ...
A conventional way to determine precipitation kinetics in heat treatable aluminium alloys is to monitor the associated solute loss by in-situ resistivity. A Gleeble machine is used to perform so called isothermal quenching (IQ) resistivity measurements. IQ ...
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 ...
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 ...
Microstructural evolution of a cold-rolled Al-Mn-Fe-Si alloy during annealing was studied. Except the as-cast variant, two other different homogenizations were considered, one gave a high density of fine dispersiods providing a considerable Zener drag infl ...
In this paper, investigation of the softening behaviour of a supersaturated Al-Mn-Fe-Si alloy during annealing after cold rolling has been carried out. Two different homogenization conditions were considered, of which one gives a condition of a large amoun ...
The physical basis and a mathematical formulation of a softening model nicknamed Alsoft, accounting for the combined effect of recovery and recrystallization during annealing of heavily deformed aluminium alloys have been presented. The prediction power of ...
The interfacial shear strength (IFSS) between nickel-titanium (NiTi) shape memory alloy wires, characterized by a nonlinear stress-strain behavior, and epoxy matrix was determined by pull-out tests. Tests were carried out at several temperatures and levels ...
