摘要

The effect of plastic deformation on the behavior of three-layer VT1-0–Al and Ti-TiB–Al composite materials manufactured by infiltration of molten aluminum 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. An Increase in VT1-0–Al composites’ reduction ratio leads to an increase in tensile strength and a decrease in plasticity characteristics. Anisotropy of ultimate strength due to the rolling direction is practically 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 cohesion strength of the layers and makes materials promising for structural elements manufacture, which are capable of maintaining integrity under plastic deformation conditions.
