Abstract

Abstract: Carbon nanotubes (CNTs) reinforced Al composites with a unique intragranular dispersion were obtained by using ultra-short CNTs. Nano-scaled CNTs were uniformly distributed inside the ultrafine Al grains. In comparison with typical CNT/Al composites with intergranular CNTs dispersion, this intragranular CNT/Al composites enable stronger dislocation pinning and retention, thereby exhibits simultaneous improvement in strength and ductility. The present intragranular dispersion strategy will provide inspirations for fabricating strong and ductile nanocarbon reinforced metal matrix composites. Graphical abstract: Image 1
