“…Возможным решением отмеченной проблемы является получение и исследование не объемных материалов, а интерметаллидных покрытий на относительно вязкой основе -титановом сплаве. Кроме того, легирование алюминидов титана кобальтом крайне редко обсуждается в научной литературе и представляет научный интерес [2].…”

“…However, only a restricted selection of materials satisfy the rigorous criteria. In this context, titanium alloys are particularly favored due to their optimal combination of properties [8,9] and are frequently utilized as replacements for jointed bones [10]. Nevertheless, titanium alloys demonstrate a significant disparity in elastic modulus (E) when compared to human bones (both trabecular and cortical), resulting in the stress-shielding phenomenon [11,12].…”

This research aims to examine how a radial graded porosity distribution affects the elastic modulus by conducting simulations on Ti-based alloy foams with face-centered cubic and body-centered cubic crystal structures. Four types of foams were analyzed; commercially pure-Ti, Ti-13Ta-6Mn (TTM), Ti-13Ta-(TT) and Ti-13Ta-6Sn (TTS), (all in at.%). Four radial graded porosity distribution configurations were modeled and simulated using the finite element analysis (FEA). The radial graded porosity distribution configurations were generated using a Material Designer (Ansys) with a pore range of 200 to 600 μm. These radial graded porosity distributions had average porosity values of 0, 20, 30 and 40%. The consolidated samples that were obtained through a powder metallurgy technique in two step samples were synthesized using a powder metallurgy technique, with the elastic moduli values of the aforementioned Ti based alloys being measured by ultrasound using ~110, ~69, ~61 and ~65 GPa, respectively. The results showed that the modulus decreased as a function of porosity level in all simulated materials. The TTM, TT and TTS foams, with average porosities of 20, 30 and 40%, exhibited an modulus smaller than 30 GPa, which is a requirement to be used as a biomaterial in human bones. The TT foams showed the lowest modulus when compared to the other foams. Finally, certain theoretical models were used to obtain the modulus, the best being; the Gibson–Ashby model (α = 1 and n = 2.5) for the cp-Ti foams and Knudsen–Spriggs model (b = 3.06) for the TTM, TT and TTS foams.

“…The powder metallurgy technique is a facile and cost-effective method that can process a net-shaped porous metal foam with a millimeter-sized pore [13]. To date, extensive works on the processing parameters have been reported on the sintering temperature, compacting pressure, the volume fraction of pore-making agents, size and shape of pore-making agents [14][15][16][17][18].…”

Porous magnesium alloy foams have gained tremendous interest from scientists because of their super lightweight, unique mechanical and physical properties. Despite numerous studies suggesting these advanced materials for structural and functional applications, their manufacturing processes remain poorly understood. In this paper, the porous Mg‐9 wt. %Al‐1 wt. % Zn alloy foam was prepared through the reactive sintering principle (i. e. the element metal powder reaction principle) by using the powder metallurgical method that is combined with a pore‐making agent. The chemical and phase compositions of the cell wall microstructure were investigated by X‐ray diffraction and scanning electron microscope equipped with energy dispersive spectrometer. The compressive properties of the foams were evaluated by quasi‐static compression testing. The results of the analysis reveal that low‐temperature sintering can produce qualitative magnesium alloy foams with good mechanical properties by taking advantage of the intermetallic/or intermediate compounds which are formed in the cell wall through metal elements powder diffusion and reaction. Particularly, the foam samples sintered at 380 °C for 12 h gave the best compressive properties owing to the alloy intermetallic contents and the relative density of the foams.
