“…At present, there are two type of preparation methods of porous NiTi alloy, namely additive manufacturing (AM) and conventional powder metallurgy (PM). Conventional PM comprises some processes such as conventional sintering, hot isostatic pressing, spark plasma sintering, and self-propagating high-temperature synthesis [ 5 , 6 , 7 , 8 , 9 , 10 ]. Nevertheless, these processes make it difficult to directly prepare products with complex shapes, and are time-consuming.…”

Porous NiTi alloys were manufactured by integration of gel-casting and microwave sintering. The effects of sintering temperature on porosity, compressive strength, pore morphology and phase composition of sintered samples were researched. The results show that the porosity and the mean pore diameter of porous NiTi alloys decrease with increasing sintering temperature, whereas the content of the NiTi phase, the elastic modulus and compressive strength of sintered samples increase. When the gel body with the solid loading of 50 vol.% is microwave sintered at 1000 °C for 30 min, porous NiTi alloys are obtained with the porosity of 38.9%, the compressive strength of 254 MPa, elastic modulus of 4 GPa, and predominant phase of NiTi. The results suggest that the method is suitable for rapid preparation of large-size and complex-shape personalized products similar to human bones at a low cost.

“…The fundamental principle for selecting porous media materials is to choose materials with good heat transfer performance, strong resistance to thermal shocks, high heat resistance, and a certain level of mechanical strength. In this study, a high-temperature resistant nonmetallic porous media material, Al 2 O 3 , is chosen as the porous media material . The parameters of the combustion chamber and porous media required for the calculations can be found in Table .…”

The combustion of conventional methane−hydrogen mixtures is associated with challenges such as combustion instability and excessive pollutant emissions. This study explores the advantages of porous media, which include a wide operating range, enhanced combustion stability, high combustion efficiency, and reduced pollutant emissions. We conducted numerical transient simulations to investigate methane−hydrogen combustion within a porous media, focusing on a cylindrical double-layer porous burner geometry. The research analyzes the temperature, combustion rate, and diffusion characteristics of the methane− hydrogen−precipitated gas flame within the porous media. Additionally, it examines variations in the position and width of the high-temperature region along with changes in carbon and nitrogen emissions. The computations were carried out for different hydrogen blending ratios over the time interval of 0−0.4 s. The results unveil the transient combustion characteristics of hydrogen-enriched methane within a porous media, offering valuable insights for the subsequent optimization of porous media burners (PMB). This study provides a theoretical foundation for enhancing the efficiency and environmental performance of combustion processes involving methane−hydrogen mixtures.

“…The given shell comprises amorphous-nanocrystalline phases of intermetallic oxycarbonitrides in the form of epitaxial strata (foamy onlay and dense bisubstrate), as reported in References [20,21]. Considering the chemical composition and structure, the shell can be classified as a cermet Ti 4 Ni 2 (O,N,C) layer [42,43,44]. In fact, such amorphous-nanocrystalline phases are implied to exhibit high corrosion resistance.…”

Porous TiNi alloys fabricated by self-propagating high-temperature synthesis (SHS) are biomaterials designed for medical application in substituting tissue lesions and they were clinically deployed more than 30 years ago. The SHS process, as a very fast and economically justified route of powder metallurgy, has distinctive features which impart special attributes to the resultant implant, facilitating its integration in terms of bio-mechanical/chemical compatibility. On the phenomenological level, the fact of high biocompatibility of porous SHS TiNi (PTN) material in vivo has been recognized and is not in dispute presently, but the rationale is somewhat disputable. The features of the SHS TiNi process led to a multifarious intermetallic Ti4Ni2(O,N,C)-based constituents in the amorphous-nanocrystalline superficial layer which entirely conceals the matrix and enhances the corrosion resistance of the unwrought alloy. In the current article, we briefly explore issues of the high biocompatibility level on which additional studies could be carried out, as well as recent progress and key fields of clinical application, yet allowing innovative solutions.
