Surface diffusion‐driven cold welding leads to intragranular dispersion and is critical for the comprehensive enhancement of composite properties in metals. Carbon nanotubes (CNTs) in metal restrain slide/climb dislocations. 1D CNTs also prevent fractures, which favor 2D percolating flaws. Article number 1800115 , by Ju Li, Young Hee Lee, and co‐workers, shows that CNTs improve the toughness and creep resistance of Al alloys without compromising electrical and thermal conductivity.
