Description
Summary:Friction deposition is one of the promising new techniques for additive manufacturing. In this work, an aluminum matrix composite reinforced with titanium particles was successfully friction deposited. The multi-layer composite friction deposits showed well-bonded layers, very fine grain size, and uniformly distributed titanium particles. While the reinforcement/matrix interfaces showed no reaction products, the layer interfaces showed thin intermetallic bands. These brittle intermetallic bands were found to strongly affect the ductility of the multi-layer composite friction deposits in the build direction. However, the composite friction deposits performed satisfactorily in compression tests as well as in single-layer tensile tests.
