In the present work, nano/ultrafine structured Al/Brass composite was produced by accumulative roll bonding (ARB) up to eight cycles. The evolution of grain refinement and deformation texture and their effect on the mechanical properties were investigated. It was observed that by increasing the ARB cycles, due to the difference in flow properties of the metal constituents, brass layers necked, ...

Three-dimensional micromagnetic simulations are used to study the effect of crystallographic textures on the magnetic properties of uniaxial nanocrystalline films of hard magnetic materials with arbitrary grain shapes and size distributions. The correlation lengths ~effective ferromagnetic exchange interaction radius and domain wall width! are assumed to be smaller than the typical grain size. ...

Design by contract is a well-established paradigm in software engineering. Bertrand Meyer first introduced the rigorous distinction between the responsibilities of service provider and service consumer for fine grain software artifacts (classes). This paper considers service contracts in the context of service-oriented architecture for complex enterprise information infrastructures. Identifying...

Abstract In the present work, results obtained in 3D polycrystal simulations are reported on coalescence effect of neighbouring grains due to texture evolution. A cellular automaton model was developed for this purpose, which permits take into account topology coalescence. The constituting were divided voxels have realistic representations grain shapes. Taylor plasticity approach applied calcul...

We investigated the role of spatial arrangement of texture elements in three psychophysical experiments on texture discrimination and texture segregation. In our stimuli, oriented Gabor elements formed an iso-oriented and a randomly oriented texture region. We manipulated (1) the orientation similarity in the iso-oriented region by adding orientation jitter to the orientation of each Gabor; (2)...

This review discusses the attempts that have been made by geologists to numerically simulate the evolution of microstructures in rocks. The strengths and weaknesses of the differing techniques are compared and equivalent materials science results are included. In particular we focus on the application of techniques that have been used to predict texture development, grain boundary geometries, d...

Tailoring recrystallization via particle-stimulated nucleation (PSN) and pinning effects from secondary phase particles effectively weakens textures, which is still challenging for low-alloyed rare earth-free Mg alloys. Herein, the texture of a dilute cold-rolled Mg-2.2Al-0.33Ca (wt.%) alloy found to reduce with appearance transverse direction (TD) components during static recrystallization. Th...

The mechanical properties of polycrystalline materials depend on the individual physical properties of the constituent grains. When grains are randomly oriented with respect to a fixed coordinate system, the average elastic properties are isotropic. A polycrystalline aggregate possesses macroscopic texture, and thus exhibit anisotropic elastic properties, when the grains are preferentially orie...
