Online acoustic emission measurement of tensile strength and wear rate for AA8011-TiC- ZrB2 hybrid composite

Abstract

Aluminum 8011 (Al 8011) titanium carbide (TiC) and zirconium boron (ZrB2) hybrid composites are stir cast in this work, and their microstructure, mechanical, and tribological properties are investigated. The matrix material was Al 8011, which was supplemented with stronger TiC to boost mechanical strength and softer ZrB2to improve thermal and corrosion resistance without significantly changing electrical properties. According to the findings, the reinforced alloy's mechanical qualities outperform those of the unreinforced alloy.Acoustic energy generated during deformation of composite materials has been monitored and early fracture measurements has been achieved using the Acoustic emission (AE) approach in tensile test specimens. As a result of the experiment, Al8011+10 % TiC+2% ZrB2composites outperform the Al8011 matrix alloy in terms of wear resistance, coefficient of friction, and surface smoothness, as well as other characteristics. The AFM representation of Al8011+10 % TiC+2% ZrB2matrix reveals that the wear surface smoothness of the AMMC is significantly improved as compared to the Al8011 matrix alloys.
