Abstract
Metal-intermetallic lamellar (MIL) composites with different intermetallic phase volume fraction (from 47 to 78 %) obtained by reactive spark plasma sintering (SPS) of Ti and Al foils enclosed in Ti shells were investigated. It was shown that increase of titanium aluminide volume fraction in the composites had no influence on their compressive strength at the loading along the layers. Compressive strength at the aforementioned loading conditions was 775 - 790 MPa. However, at the loading of materials in the direction perpendicular to layers the compressive strength value raised from 655 to 760 MPa with increase of titanium volume fraction in the material.
