Study of the process of titanium-containing furnace charging material compaction by an experimental-analytical method

Abstract: Исследована зависимость пористости порошкового материала на основе губчатого титана от коэффициента напряженного состояния в процессе пластического деформирования с преобладающим действием всестороннего сжатия. На основе результатов, полученных в предшествующих работах, на плоскости σ-T построено семейство кривых текучести с варьируемой пористостью. Условие текучести порошкового материала основано на модели пластического течения Modified Drucker-Prager Cap model. На графике геометрической интерпретации принято… Show more

“…This approach will enable avoiding a critical error in the presentation of the distribution of loading on a particle in modeling the structure formation of powder composites [8][9][10][11] when the number of contact points does not correspond to the actual one. Though the model of space filling by Kelvin [24], applied by researchers [13] while modeling the load on a given particle, is reasonable, the cluster cuboctahedral model makes it possible to describe the actual processes more accurately.…”

“…However, both cases did not take into consideration such a decisive factor as powder particle arrangement in the pressing. In addition, the model of their packing, which was the basis for the calculations [9,11], has a cubic lattice, which does not correspond to the actual structure of packing spherical particles in the densest pressing.…”
