Abstract

Layered packages consisting of 50 µm thick Al and Ti foils were used for producing metal-intermetallic laminate composites by a reactive sintering. The sintering was conducted at 630℃ and at a pressure of 25 MPa under the action of pulsed or direct current, which allowed the accelerated production of Ti/TiAl₃ metal-intermetallic laminate composites without melting Al layers. Optimal characteristics of the electrical current flow through the 1–3 mm thick packages enabling the sintering time reduction by the factor of 1.5–2 as compared to the static hot pressing have been found. Possible mechanisms of the electrical current influence on solid-phase reactions in the laminate systems include Joule heating, the grain boundary electromigration, and the electroplastic effect.
