Modeling of Continual Flows in Angular Domainsristoffel’s (S—C) integral method. In complex form such important kinematical parameters as vector velocity, strain rate and shear strain degree are obtained. These parameters are used as a basis for determining corrected parameters by the standard procedure of simulating the actual metal motion in

Synthesis and Characterization of Nanocrystalline Tial Based Alloysng) and hot isostatic pressing (HIP’ing). MA’ing in a high-energy mixer mill led to severe plastic deformation and amorphization of the powder particles. The γ-TiAl alloys produced from the amorphous powders had a nanocrystalline structure. The grain size increased when the HIP temperature and time

Formation of Submicrocrystalline Structure in TiAl and Ti3Al intermetallics via Hot Working (d < 1 µm) in massive work-pieces of hard-to-deform materials, like titanium aluminides, The method involves continuous grain refinement due to dynamic recrystallization at a decreasing temperature. A microstructure with a grain size of 0.1 to 0.4 µm and no porosity was produced in different TiAl a

Severe Plastic Deformation Processes: Modeling and Workabilityd. The majority of research on the modeling of the equal channel angular extrusion (ECAE) process invented by Segal has focused on the kinematics of metal flow under nominally frictionless conditions. Physical (visioplasticity) models suggest that such assumptions yield reasonable estimates of impos

Size Distribution of Grains or Subgrains, Dislocation Density and Dislocation Character by Using thenous function of the diffraction angle. The lack of a physically sound model makes the interpretation of line broadening difficult or even impossible. Dislocations are anisotropic lattice imperfections with anisotropic contrast effects in diffraction. It has been suggested recently that anisotropic

X-Ray Studies and Computer Simulation of Nanostructured SPD Metalsaid to X-ray investigations of microstructure evolution in bulk nanostructured samples of pure Cu obtained by SPD processing by torsion under high applied pressure and equal channel angular (ECA) pressing. Computer simulation is used to analyze the X-ray results.
