Journal cover:Intragranular Dispersion of Carbon Nanotubes Comprehensively Improves Aluminum Alloys
July 18, 2018. (Adv.Sci.2018)
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.
