Influence of rolling on the structure and properties of layered Ti–Al composite materials manufactured by aluminium melt infiltration

The effect of plastic deformation on the behavior of three-layer VT1-0–Al and Ti-TiB–Al composite materials manufactured by aluminum melt infiltration is investigated. The microstructure of the interaction zone between titanium and aluminum layers is studied. The transition layer is fragmented and fracture zones which are formed in titanium layers are filled with plastic aluminum during rolling. Increase of VT1-0–Al composites compres-sion ratio leads to increase of tensile strength and decrease of plasticity characteristics. Aniso¬tropy of ultimate strength due to the rolling direction practically is not observed. Fracture of VT1-0–Al and Ti-TiB–Al composites as a result of the tensile process does not lead to significant delamination, which indicates a high bond strength of the layers and makes materials promising for structural elements manufacture, which are capable of maintaining integrity under plastic deformation conditions.
