Synergistic Strengthening Effect of Ultrafine-Grained Metals Reinforced with Carbon Nanotubes

From strength to strength: Two strengthening mechanisms, grain‐size refinement of a metal matrix and reinforcement with homogeneously dispersed CNTs, are combined to fabricate strong CNT/Co nanocomposites (see image). The CNT/Co nanocomposites with an ultrafine‐grained Co matrix and homogeneously di...

Description
Summary:From strength to strength: Two strengthening mechanisms, grain‐size refinement of a metal matrix and reinforcement with homogeneously dispersed CNTs, are combined to fabricate strong CNT/Co nanocomposites (see image). The CNT/Co nanocomposites with an ultrafine‐grained Co matrix and homogeneously dispersed CNTs show synergetic strengthening effects with improved mechanical performance.
