With a membrane based mechanism to allow for pressure change in a sample in a radial diffraction diamond anvil cell and simultaneous infrared laser heating, it is now possible to investigate texture changes during deformation and phase transformations over a wide range of temperature-pressure conditions. The device is used to study bcc , fcc , and hcp iron. In bcc iron, room temperature compres...

The D00 region that lies just above the core mantle boundary exhibits complex anisotropy that this is likely due to preferred orientation (texturing) of the constituent minerals. (Mg,Fe)SiO3 post-perovskite is widely thought to be the major mineral phase of the D00. Texture development has been studied in various post-perovskite phases (MgSiO3, MgGeO3, and CaIrO3), and different results were ob...

The ZK61 alloy rods with different grain sizes and crystallographic texture were successfully fabricated by cyclic extrusion and compression (CEC). Their room-temperature tension & compression yield strength displayed a significant dependence on grain size and texture, essentially attributed to {10-12} twinning. The texture variations were characterized by the angle θ between the c-axis of ...

Wrinkle simulation with skin modeling and deformation are extremely important in enhancing the realism of human figure models. In this paper we present a model which simulates the skin deformation based on a biomechanic model and generates dynamic wrinkles rendered with texture image. The biomechanical model considers the skin as a membrane undergoing large deformations and puts the local coord...

An AM30 magnesium alloy was processed through ECAP method at 200 °C. Optical and transmission electron microscopy as well as electron back scattered diffraction (EBSD) technique were employed to characterize the deformed microstructure. A partially recrystallized microstructure including ultrafine/nano structures was obtained. The area fraction of 49% was measured for the recrystallized regions...

A new volume deformation technique using FEM and voxel-texture (voxture) maps has been developed. In contrast to the traditional deformation techniques, the new algorithm is aimed at volume transformations, deformations and volume metamorphosis.

Image-based texture overlay or retexturing is the process of augmenting a surface in an image or a video sequence with a new, synthetic texture. Some properties of the original texture such as texture distortion as well as lighting conditions should be preserved for a realistic appearance of the augmented result. One approach would be to estimate a 3-dimensional geometry of the surface. However...

This paper is a contribution to the recovery of shape from texture under perspective projection. We regard shape from texture as a statistical estimation problem, the texture being the realization of a stochastic process. There are two minimal conditions in order for the problem to be solvable: the first is a stationarity condition on the texture with respect to the surface; the second is the r...

An investigation has been carried out on the texture of Ti-44Ni-5Cu (at %) shape memory alloy wire. The texture of the B2 and monoclinic phases has been determined as a function of the degree of cold deformation during the drawing process and the number of cycles on thermomechanical cycling. After cold drawing and anlealing (823 K, 180 s ) under tensile stress, the [110], [li~] [loll and [loll ...

Heavily rolled in-situ MMCs of Cu-20 vol% Nb have been investigated by means of quantitative texture analysis mainly for three reasons. First, the crystallographic texture can be very sensitive to the deformation process. Second, the orientation distribution affects the strength of the material in terms of the Taylor factor. Third, the influence of a massive second phase on texture development ...
