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

Ke Huang, Ning Wang

Using different homogenization treatments, different initial microchemistry conditions in terms of solid solution levels of Mn, and number densities and sizes of constituents and dispersoids were achieved in an Al-Mn-Fe-Si model alloy. For each homogenized ...

A review of dynamic recrystallization phenomena in metallic materials

Roland Logé, Ke Huang

The dynamic recrystallization (DRX) phenomena occurring in different thermo-mechanical processing (TMP) conditions for various metallic materials are reviewed. Several types of DRX are described: discontinuous dynamic recrystallization (DDRX), continuous d ...

Orientation Preference of Recrystallization in Supersaturated Aluminum Alloys Influenced by Concurrent Precipitation

Ke Huang

The influence of concurrent precipitation on recrystallization is analyzed by comparing the nucleation and growth behavior of P ({011} 〈566〉), Cube ({001} 〈100〉), and 20 deg ND-rotated Cube ({001} 〈310〉, NDcube)-oriented grains in Al-xMn-Fe-Si (x = 0, 0.4, ...

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 ...

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

Ke Huang

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 ...

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

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

En route to multi-model scheme for clinker comminution with chemical grinding aids

Mark Sawley, David Geissbühler, Emmanuel Gallucci

We present a multimodel simulation approach, targeted at understanding the behaviour of comminution and the effect of grinding aids in industrial cement mills. On the atomistic scale, we use molecular dynamics (MD) simulations with validated force field mo ...

Deformation mechanisms and rheology of serpentines in experiments and in nature

Elodie Adeline Amiguet

Microstructures in serpentine samples recovered from deformation experiments performed at high pressure (1-8 GPa), high temperature (150-500 degrees C), and laboratory strain rates (4 10(-4)-10(-6)s(-1)) were studied using transmission electron microscopy ...

cgDNA: a software package for the prediction of sequence-dependent coarse-grain free energies of B-form DNA

John Maddocks, Daiva Petkeviciute, Marco Pasi

cgDNA is a package for the prediction of sequence-dependent configuration-space free energies for B-form DNA at the coarse-grain level of rigid bases. For a fragment of any given length and sequence, cgDNA calculates the configuration of the associated fre ...

Dynamic fracture testing methods and fracture behaviour of rock materials

Qianbing Zhang

The purpose of this review is to present the state-of-the-art in dynamic fracture testing methods and fracture behaviour of rock materials. The review begins by briefly introducing the history of rock dynamic fracture and explaining the significance of stu ...

Biaxial texture development in aluminum nitride layers during off-axis sputter deposition

Paul Muralt

Polycrystalline aluminum nitride (AlN) layers were deposited by pulsed-dc reactive magnetron sputtering from a variable deposition angle alpha = 0 degrees-84 degrees in 5 mTorr pure N-2 at room temperature. X-ray diffraction pole figure analyses show that ...
