摘      要：The 5.0 vol.%GNP/2024Al composites were prepared by accumulated shear deformation combined with heat treatment,*** thermomechanical treatment(TMT).The results showed that homogeneous distributed GNPs that aligned along the plastic deformation direction were obtained by six-pass drawing in the solution heat treatment *** introducing of high-density dislocations in Al matrix by multiple drawing resulted in enhanced nucleation of precipitates and subsequent uniform growth during ***,ultra-strength GNP/2024Al composites,with yield and ultimate tensile strength 482 and571 MPa,respectively,were *** high strength was attributed to homogeneous dispersion of undamaged GNPs,fine and dispersed precipitations and work-hardening *** work demonstrated that TMT could act as a feasible strategy for preparing high-performance GNP/Al composites.
