摘要
Abstract
The composite materials of 3% (mass fraction)carbon nanotubes(CNTs)/Al5083 were fabri‐cated by high‐energy ball milling and cold rolling .The surface morphology of the composite powder of ball milled was observed using SEM and TEM ,the phase of composite powder and composite material w ere analyzed by Raman spectrum and XRD .Finally ,the mechanical properties of composite material were tested .The results show that ,the CNTs have a good structure and are well‐distributed in the for 1 .5h milled aluminum matrix .The composite material exhibits high strength for the tensile strength of 278MPa ,yield strength of 247MPa and elongation rate of 0 .07 ,Vickers hardness of 95 .Compared with the predicted value of yield strength by thermal mismatch model and Orowan model ,the experi‐ment value indicates that the mechanism of CNTs/Al5083 accords with Orowan mechanism .关键词
