“…One variant of lowering the prime cost of titanium wares with physicomechanical properties close to those regulated for technical titanium is the pressure treatment of sponge omitting the operation of smelt ing the ingots [2,3]. The authors of [4][5][6] proposed the fabrication technologies of consumed electrodes from titanium sponge.…”

Металловедение и термическая обработка Известия вузов. Цветная металлургия • № 2 • 2015 ВведениеТитан обладает комплексом уникальных свойств, которые обуславливают его использование для из-готовления изделий в авиа-и ракетостроении, во-енном и гражданском судостроении, энергетике. Области применения этого металла и в других от-раслях промышленности могли бы быть существен-но расширены при снижении стоимости титановых изделий, которая определяется энергозатратной многоступенчатой технологией производства.

E-mail: nav@imach.uran Исследовано влияние водородного легирования на свойства брикетов, полученных из титановой губки компактировани-ем в закрытой пресс-форме при температурах 170, 325, 400 °C и давлении 1000 МПа. Полученные результаты показывают целесообразность использования эффекта водородного пластифицирования при изготовлении квазимонолитных загото-вок из некомпактного сырья в виде титановой губки методами обработки давлением.Ключевые слова: титановая губка, компактирование, термоводородное легирование.The influence of hydrogen alloying on the properties of briquettes fabricated from titanium sponge by compaction in a closed mold at temperatures of 170, 325, and 400 °C; and a pressure of 400 MPa. Our results show reasonability of using the hydrogen plasticizing effect when fabricating quasi-monolith billets from noncompact feedstock in a form of sponge by pressure treatment methods.

“…With a lateral relative displacement of the adjacent particles at the shear deformation, oxide films are removed, resulting in the formation of contacts between juvenile surfaces. To extend the shear component of deformation during hot stamping, the molds of a special design with "outflow elements mode" are used [15]. In this case, a density of 99.8-100% is achieved with a pressure of 560-650 MPa, while the density does not exceed 98-98.5% when stamping in a closed die with a pressure of 700-800 MPa [16].…”

A novel method of the hot consolidation metal powders with shear deformation is proposed. The powders were encapsulated into tight containers and compacted after short-term heating in a furnace preheated to 900 °C. The method prevents powder oxidation, peripheral spalling and ensures the removal of the oxide films from the powder surfaces. Commercial titanium powders of different dispersivities and impurity concentrations were hot-compacted. The microstructure, hardness and bending strength of the compacts were investigated. The compacts from fine PTOM-1 powder, containing 0.32% of hydrogen, reveal the greatest values of the hardness and bending strength. Additional annealing results in 60% increase in the bending strength.

“…The possibility of manufacturing titanium products with the required properties, obtained by solid-phase consolidation technology of a titanium sponge, is shown in numerous studies [9][10][11][12][13][14][15][16]. The favorable effect of preliminary thermohydrogen treatment for the compactibility of a titanium sponge at certain temperatures has been first studied and shown in [17,18].…”

The paper discusses the material compaction process under various types of stress conditions based on the simulation of the multiaxial compression process of powdered titanium sponge. The finite element model of the multiaxial compression process made it possible to apply both radial and axial pressure independently from one another. Titanium sponge subjected to reversible thermo-hydrogen processing was used as the research material. For the description of the material plasticity condition, the modified Drucker-Prager Cap plasticity model was used, implemented in Abaqus.
