Abstract

Al-2 vol pct fullerene (C60) composites with relative densities of >0.98 are manufactured by high-pressure torsion of ball-milled powders under an applied pressure of 6 GPa. A considerable Al grain refinement to ~53 nm and a homogeneous distribution of fullerenes give rise to a very high hardness of 152 Hv and yield stress of 405 MPa. Nevertheless, the poor tensile ductility due to the low work-hardening rate is achieved.
