Microstructure and Mechanical Properties of CNT-Reinforced AZ31 Matrix Composites Prepared Using Hot-Press Sintering
Source abstract
Abstract
AZ31 matrix composites reinforced by carbon nanotubes (CNTs) were fabricated using hot-press sintering. The microstructure and mechanical properties of the composites (denoted as Mg-3wt.%Al-1wt.%Zn-xwt.%CNTs, x = 0-1.5) were investigated. The results showed that the elastic modulus, yield strength, tensile strength and elongation of the composites were significantly improved when compared with the matrix alloy AZ31. Of the tested composites Mg-3wt.%Al-1wt.%Zn-1.0wt.%CNTs exhibited the most favorable mechanical properties: compared with Mg-3wt.%Al-1wt.%Zn, the elastic modulus improved by 25.85%, yield strength increased by 23.48%, and tensile strength and elongation showed 19.35 and 48.23% improvement, respectively. The fracture surface of the Mg-3wt.%Al-1wt.%Zn-CNTs composites displayed features of brittle fracture, which suggests that CNTs do not markedly enhance the plasticity of AZ31.
