Fabrication of high strength carbon nanotube/7055Al composite by powder metallurgy combined with subsequent hot extrusion

Improving the elevated-temperature mechanical properties of AA3004 hot-rolled sheets by microalloying with Mo and optimizing the process route

“…4c and d. The formation of dispersoids in the bright bands could be attributed to dislocations induced by the large plastic deformations occurring during hot rolling, which promoted dispersoid precipitation [25,28].…”

Improving the high-cycle fatigue strength of heterogeneous carbon nanotube/Al-Cu-Mg composites through grain size design in ductile-zones

“…However, the CNT/Al composites have a significant drawback of low ductility, which limits their industrial application. This is mainly due to the lower dislocation storability of the fine grains, and the strong pinning effect of CNTs on dislocation gliding [19][20][21].…”

Structure optimization for improving the strength and ductility of heterogeneous carbon nanotube/Al–Cu–Mg composites

“…Therefore, they are considered as ideal reinforcements for metals. In the past decade, many studies have shown that the strength and modulus of CNT/Metal composites could be enhanced compared with those of the matrixes [3][4][5][6][7][8][9][10]. The major strengthening mechanisms of CNT/Metal composites are the load transfer from the matrix to CNTs and the grain refinement caused by CNT addition [11][12][13][14][15][16][17][18][19].…”
