Abstract & Overview
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.
