Abstract: | The morphology of the surface and fracture of highly porous materials obtained during the thermal destruction of metalorganic
mixtures (MOM) was investigated. The size and shape of pore channels in the finished product were shown to be determined through
the fractional composition and the particle shape in MOMs. The effect of the porosity on the permeability and strength of
sintered materials was considered. The permeability was demonstrated to depend not only on the value, but also on the shape
of pore channels. Combining the techniques of powder metallurgy with chemical-metallurgical processes allows us to obtain
materials with a porosity of 70–80% and a strength of no less than 5–25 MPa. If the pore size was from 10 to 100 μm, the permeability
of materials was (in 10−12 m2) 1–3 for Mo, 0.5–6 for Mo-Ni, and 2–6 for Ti-Mo. |
