摘要：
An effective approach is utilized to establish a strong interface between the carbon nanotube (CNT) and the Cu matrix by introducing the matrix-alloying chromium (Cr) element. The interface microstructure and mechanical properties of the composites are characterized by high-resolution transmission electron microscopy (HRTEM), hardness and tensile tests, respectively. Compared to CNT/Cu composites, CNT/CNT-Cr composites show evenly improved interfacial bonding and enhanced mechanical properties, which is ascribed to the formation of thin intermediate Cr3C2 transition layer between CNTs and Cu-Cr matrix.
