Titatium-Flake Reinforced Aluminum-Matrix Composite Prepared from Multilayered Foils by Cold Pressure Welding

Abstract

In the present work, pure aluminium foils 92 μm thick and pure titanium foils of three thicknesses were alternately multilayered and then pressed at high pressure at room temperature to fabricate aluminium matrix al/ti composites of three volume fractions by a simple method. The composites were examined by optical and scanning electron microscopy and by nominal compressive stress-displacement curves. Tensile and bending properties were investigated. Tensile strengths of the composites were compared with the values estimated from the rule of mixtures on the flake-reinforced composite
