Increasing Polycrystalline Zinc Oxide Grain Size by Control of Film Preferential Orientation

Christophe Ballif, Cécile Hébert, Aïcha Hessler-Wyser, Duncan Thomas Lindsay Alexander, Sylvain Nicolay, Monica Morales Masis, Lorenzo Fanni, Arthur Brian Aebersold

We investigate the structural evolution of polycrystalline zinc oxide films grown by low pressure metal-organic chemical vapor deposition. The goal is to achieve larger grains-leading to higher charge carrier mobility from lower grain boundary density-by c ...

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 ...

Microstructural characterizations of 14Cr ODS ferritic steels subjected to hot torsion

Roland Logé

Oxide dispersion strengthened (ODS) steels are very promising materials for nuclear applications. In thispaper, the hot working behavior of ODS ferritic steels, consolidated by hot extrusion, is studied through torsion tests. Three ODS steels are produced ...

A mean field model of dynamic and post-dynamic recrystallization predicting kinetics, grain size and flow stress

Roland Logé, Ke Huang

A physically-based two-site mean field model has been developed to describe the microstructural evolution due to recrystallization during and after deformation. The model has been applied to predict the recrystallized fraction, recrystallized grain size, a ...

Factors affecting the strength of P{011}〈566〉-texture after annealing of a cold-rolled Al–Mn–Fe–Si alloy

Ke Huang

Elongated coarse P{011}-oriented grains are frequently observed after annealing of cold-rolled Al–Mn alloys with a highly supersaturated solid solution level. In this study, important factors affecting the strength of the P-texture component after ann ...

Microstructural influence on the scatter in the fatigue life of steel reinforcement bars

Alain Nussbaumer, Marina Rocha Pinto Portela Nunes

Fatigue damage accumulation and failure of steel reinforcement bars (rebars) is a stochastic process. Scatter can be influenced by the sensitivity of the short crack growth to the microstructural features, especially near the fatigue limit. This work inves ...

The influence of microchemistry on the recrystallization texture of cold-rolled Al-Mn-Fe-Si alloys

Ke Huang

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 ...

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 ...

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

Roland Logé

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 ...
