Effect of heterogeneously distributed pre-existing dispersoids on the recrystallization behavior of a cold-rolled Al–Mn–Fe–Si alloy

It is well known that strong concurrent precipitation, mainly located along grain/subgrain boundaries, results in a coarse and elongated grain structure, and unusual sharp P {011} and/or M {113} texture components during annealing of supersatur ...

Evaluation of the interfacial shear strength between pseudoplastic NiTi shape memory alloy wires and epoxy by the pull-out method

Véronique Michaud, Yves Leterrier, Edgars Sparnins

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 ...

Influence of temperature and wetting angle on capillarity in pressure infiltration

Andreas Mortensen, William Craig Carter, Ludger Weber, Alain Léger, Gionata Schneider

Capillary forces in the pressure infiltration process can be quantified by measuring saturation curves; these are plots of the fraction pore space filled with the liquid infiltrant versus the pressure difference between the liquid and the atmosphere initia ...

Prediction of quenching-induced stress distribution in 7XXX aluminium alloy thick plates using Gleeble interrupted quench tests

Jean-Marie Drezet, Nicolas Paul Henry Chobaut, Patrick Schloth, Denis Carron

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 ...

In situ X-ray Diffraction during Casting: Study of Hot Tearing in Al-Zn alloys

Jean-Marie Drezet, Güven Kurtuldu, Bastien Gilbert Pierre Mireux

During solidification of metallic alloys, coalescence corresponds to the formation of solid bridges between grains when both solid and liquid phases are percolated. As such, it represents a key transition with respect to the mechanical behaviour of solidif ...

Modeling of percolation of globular-equiaxed grains in Al-Cu alloys

Michel Rappaz, Jean-Luc Desbiolles, Christophe Mondoux

A new mesoscopic model able to describe percolation of globular-equiaxed grains, highly relevant for hot tearing formation in castings, has been developed. This model is inspired from the granular model of Sistaninia et al. [1-5] that considers polyhedral ...

Evolution in microstructure and properties during non-isothermal annealing of a cold-rolled Al-Mn-Fe-Si alloy with different microchemistry states

Ke Huang

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 ...

Electric-Field-Induced Domain Switching and Domain Texture Relaxations in Bulk Bismuth Ferrite

Dragan Damjanovic

Bismuth ferrite, BiFeO3, is an important multiferroic material that has attracted remarkable attention for potential applications in functional devices. While thin films of BiFeO3 are attractive for applications in nanoelectronics, bulk polycrystalline BiF ...

The Influence of Microchemistry and Processing Conditions on the Softening Behavior of Cold-Rolled Al-Mn-Fe-Si Alloys

Ke Huang

Motivated by an increased focus on recycling of aluminium alloys, for which elements like Mn, Fe and Si tend to increase, a comprehensive investigation of the softening behavior during annealing after cold rolling of Al-Mn-Fe-Si alloys has been carried out ...

Influence of the wetting angle on capillary forces in pressure infiltration

Andreas Mortensen, Ludger Weber, Alain Léger

This work probes the influence of wetting on pressure infiltration. Pressure/saturation curves for the infiltration of packed F1000 angular alumina particle preforms by liquid Cu-Al and Sn-Al alloys are measured using an instrumented high-temperature press ...
