MECHANISMS OF DYNAMIC REARRANGEMENT OF THE DEFECT SUBSTRUCTURE OF INDUSTRIAL STEELS

Using transmission electron microscopy methods the layer by layer analysis of the bulk hardened superior quality rails is carried out and the quantitative parameters of structure, phase state and defect substructure gradients are established. It is shown that the interface boundaries globular cementite particles-matrix are the possible places of microcracks initiation.

The data of the study of the elemental and phase composition, the condition of the defect substructure, mechanical and tribological characteristics of titanium alloy VT6 subjected to electroexplosive carburization with a sample of titanium diboride powder and the subsequent treatment by high-intensity pulsed electron beam is presented. It has been established that the main mechanisms responsible for an increase in the mechanical and tribological properties of the material are solid, dispersion, and grain boundary.

Before And After

Commercial nanopowder of the partially yttrium-stabilized zirconia (ZrO2+3 mol.% Y2O3) was treated by the non-cavitational powerful ultrasonic action (PUA). Influence of PUA on the microstructure and phase composition of the powder has been investigated by scanning and transmission electron microscopy. Investigated powder before and after PUA has polycrystalline structure. It was found that TZ-3YS particles after PU-treatment have tetragonal and cubic zirconia phases; some of the particles consist of a mixture of monoclinic, tetragonal and cubic phases, but these particles have substructure with random orientation of fragments.
