Ultrafine-Grained Ti-13Nb-13Zr Alloy Produced by Severe Plastic Deformation [PDF]
Materials Research, 2017 Biomedical devices currently in use (prostheses, implants) have satisfactory performance in many cases. However, sometimes the body reacts to the device insertion and may lead to its rapid replacement. Some of these disadvantages can be solved by the use

SIMULATION OF THE SEVERE PLASTIC DEFORMATION PROCESS IN NANOCRYSTAL ON THE BASIS OF INTERMETALLIDE [PDF]
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2012 The mechanisms of structural transitions in a nanocrystal on the basis of intermetallic Ni3Al was studied by means of simulation of the process of the severe plastic deformation. For the structure analysis we used the simplexes of Voronoi-Delaunay, which

Severe plastic deformation and phase transformations [PDF]
Journal of Physics: Conference Series, 2010 Large densities of crystalline defects are created in severely deformed metallic alloys, pushing systems far from the thermodynamic equilibrium. Thus, strain induced phase transformations may occur and affect the mechanical properties like in the well known white etching layer on the surface of rail tracks.
