Al UFG particles were mixed with B4C nanoparticles and consolidated using cyclic forward-backward extrusion as a novel severe plastic deformation process to produce Al–B4C UFG composites full densification initial billets. Continue process of deformation by hydrostatic extrusion conducted on initial billet to produce UFG composite tubes with high strength properties. The Al particles were mixed with 5 and 10 wt.% B4C particles, by mechanical milling. The mixed powders were consolidated at 250C by cyclic forward-backward extrusion into fully dense bulk composite materials, resulting in significantly higher strength as well as good creep properties in the produced composites tubes.
