Abstract
The study deals with the structure and mechanical properties of compos ites made of porous aluminum and AL2 alloy impregnated with dispersed particles of TiO2. Studied were the effect of hot extrusion on shape, size and volume fraction of pores in porous composites. Obtained were curves of strain hardening of composites at 20, 300 and 500 degrees C, strain rates varying from 1.5 10(-2) to 10(-1). It was shown that the composite obtained from AL2 alloy possesses adequate high-temperature properties.
