Description

Made rigging for quasihydroextrusion (QHE) with backpressure at cryogenic (77 К) temperatures of purveyances from Zr, Ti and their alloys of diameters to 20 mm. Certain routes of deformation dragging, rolling and КГЕ, that provide normal motion of treatments. Deformation rolling and drawing in cryogenic conditions (77 К) for iodine titan and alloy of VТ6 provides diminishing of structure to ?70 нм and increase of strength properties on 25% at maintenance of plasticity at the level of 10%. Set correlation of mechanical properties and thermo-emf for titan. For the nanostructured alloy of ВТ6 (cryogenic rolling) as compared to the state after isothermal forging at the increased temperatures is set the features of dissipative properties in region of temperatures 300-600К. Kinetics of evolution of vacancy clusters which arise up in titan at intensive flowages in cryogenic conditions studied in theory.
