CNT/2024A1 composite reinforced with different CNT contents was fabricated by high-energy ball-milling and powder metallurgy method.The micro structure and mechanical properties of the composite,the change of mixed powder were analyzed.The results show that a certain mass of CNT uniformly disperse in 2024A1 matrix by ball-milling.The composite reinforced by 2wt%CNT exhibits the best mechanical performance,the yield strength is improved by 20.28%compared with 2024A1 matrix.When CNT mass fraction reaches 3wt%...
