Multipass forging of Inconel 718 in the delta-Supersolvus domain: Assessing and modeling microstructure evolution

This work is focused on the evolution of the microstructure of Inconel 718 during multi-pass forging processes. During the forming process, the material is subjected to several physical phenomena such as work-hardening, recovery, recrystallization and grai ...

Monitoring precipitation kinetics in heat treatable aluminium alloys using in-situ resistivity in Gleeble thermomechanical simulator

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

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 ...

The influence of microchemistry on the softening behaviour of two cold-rolled Al–Mn–Fe–Si alloys

Ke Huang, Ning Wang

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 ...

Isothermal annealing of cold-rolled Al–Mn–Fe–Si alloy with different microchemistry states

Ke Huang

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 ...

Solute strengthening of twinning dislocations in Mg alloys

William Curtin, Maryam Ghazisaeidi

Solute strengthening of twin dislocation motion along an existing twin boundary in Mg–X (X = Al, Zn) is investigated using a new Labusch-type weak pinning model. First, the View the MathML source(101¯2) twinning dislocation structure is computed using firs ...

Prediction of Hot Tear Formation in Vertical DC Casting of Aluminum Billets Using a Granular Approach

Michel Rappaz, Jean-Marie Drezet, André Phillion, Meisam Sistaninia

A coupled hydromechanical granular model aimed at predicting hot tear formation and stress-strain behavior in metallic alloys during solidification is applied to the semicontinuous direct chill casting of aluminum alloy round billets. This granular model c ...

3-D granular modeling and in situ X-ray tomographic imaging: A comparative study of hot tearing formation and semi-solid deformation in Al-Cu alloys

Michel Rappaz, Jean-Marie Drezet, André Phillion, Meisam Sistaninia

The mechanical behavior of partially solidified Al-Cu alloys is investigated to assess the influence of mushy zone deformation on hot tearing. For this purpose, the results of a semi-solid tensile test conducted in situ using X-ray microtomography are comp ...

W-2 wt.%Y2O3 composite: Microstructure and mechanical properties

Philippe Spätig, Nadine Baluc, Robin Schäublin

A W-2Y(2)O(3) composite is produced by powder metallurgy, including the pressing of the mixed elemental powders, their sintering and hot forging. The microstructure of the obtained composite is investigated using light microscopy, scanning electron microsc ...
