Global And Local

Silver of 3N purity was deformed at room temperature by equal channel angular pressing (ECAP) using three passes of route A. The global and local texture were investigated by neutron diffraction and high-energy synchrotron radiation, respectively. The texture is characterized by typical simple shear components of fcc metals which differently deviate from their ideal positions. Local texture measurements reveal that the intensity and inclination of the texture components with respect to the extrusion direction depend on the distance from the top of the extruded bar and change from pass to pass. Reasons for the texture gradient are discussed. The texture of silver is compared with that of copper having a higher stacking fault energy.

Thin Walled

The origami is transforming a flat sheet into some other shapes. It extends the mechanical properties of thin walled shells by introducing a local texture pattern, with surface features at a scale intermediate to the material and its structure. The primary application of local texture in thin-walled shells has been to increase the shell’s bending stiffness, their ability to absorb impact through plastic deformation of the texture pattern and in plane flexibility.

Bulk Nanocrystalline

A bulk nanocrystalline (nc) Ni–Fe alloy was subjected to tensile deformation, which leads to grain growth. The nanoindentation study indicates that the hardness, H, and Young’s modulus, E, of the nc alloy before and after tensile deformation did not show a clear indentation-rate effect. However, the tensile deformation results in a decrease in the E values of about 15%, which might be attributed to the grain rotation, leading to texture development during the stress-induced grain growth.

Mechanisms Of Plastic Deformation

Rolled single crystals of the alloy Ti–48%Ni–2%Fe were studied by methods of X-ray diffractometry using a PSD-technique. Single crystals, consisting of the phase B2, were rolled in 11 initial orientations at 350°C with deformation degrees up to ~80%. Texture development in single crystals under rolling was analyzed to determine the acting mechanisms of plastic deformation. Three stable orientations of single crystals were found: {011}〈011〉 ,{111}〈011〉 and {111}〈112〉. It was shown on the basis of texture data, that Ti–Ni single crystals deform by means of combined action of slip in the systems {011}〈001〉 and twinning. For the first time, along with twinning in the known systems {114}〈221〉 , twinning in the systems {118}〈441〉 was revealed. A number of concrete cases was considered to refine the contributions of slip and twinning into reorientation of single crystals depending on their initial orientations as well as to ascertain the interrelation of different mechanisms.
