5052 aluminum alloy matrix/titanium composites with about 8, 18 and 47 volume percents of titanium were fabricated by a simple method; compressing alternately multilayered 5052 aluminum alloy foils and pure titanium foils at room temperature. The initial thickness of titanium foils was 10, 25 or 102 μm and that of 5052 aluminum alloy foils was 115 μm. The composites obtained show the multilayered structure of the aluminum alloy and pure titanium phase extended in two dimensions. Many cracks are generated in titanium foils with the initial thickness of 10 μm during compressing and the number of cracks formed decreases with increasing thickness of titanium foils. No crack is detected in titanium foils with thickness of 102μm. Interlaminar shear strength between the aluminum alloy and titanium phases increases with the volume fraction of titanium phase and with the total reduction. The measured values of tensile strength of the composites are nearly in agreement with the values estimated from the rule of mixture on continuous-reinforced composites.
