Information on the production technology of powder titanium Ti6,1Al5,4V1,8Sn alloy, as well as results on the effect of heat treatment on its the structure, phase composition and properties are presented. It is shown that for powder product it is possible to recommend the heating temperature of the workpieces 900...950 °C, heating of the stamp to 850...900 °C with the elongation coefficient μ l 9. Increase in the extrusion temperature of the workpiece above 950 °С does not give significant increase in density and, at low elongation coefficient, leads to grain growth of the metal structure. The effect of quenching and melting temperatures on the decomposition of α′-martensite, precipitation of the α2-phase Ti3Al and, in particular, during quenching of alloy specimens from the β-region, as well as in the case of quenching from (α + β)-state is studied.

Main Component

We prepared Solid silicon nitride nanowires using carbon nanotubes as precursors., Si and SiO2 were used as raw materials,the reaction was carried out in ammonia atmosphere The structure, phase composition, ESR properties and oxidation resistance of the sample were investigated. The results showed that the sizes of the nanorods are 60–80 nm in diameter and up to several microns in length. In the products α-Si3N4 is the main component; the FTIR spectra of the silicon nitride nanowires have blue shift phenomena;The ESR properties show that the as made materials contains a large number of unpaired electrons
