During sintering of compacts of mixtures of powdered titanium and iron, and also of powdered titanium, iron, and nickel, the processes of formation of intermetallic compounds at temperatures below the eutectic temperature proceed as a result of solid-phase interaction between the components. The intensity of this interaction increases in dependence on the increase of the degree of dispersity of the powders that are used. Sintering at temperatures higher than the eutectic temperature is accompanied by the active formation of intermetallic compounds. The temperature ranges of intensive formation of intermetallic compounds in the systems titanium-iron and titanium-iron-nickel correspond to the temperatures of abrupt change of direction and speed of the sintering process on the dilatometric curves and to the appearance of exothermal peaks on the DTA curves. |
