Abstract In current scenario the aircraft industry in need of a lightweight connecting material that persuade the technical and technological standards, but also need superior mechanical qualities. In this work the major objective is to enhance the strength behaviour of stir cast composites. 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 ZrB2 to 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% ZrB2 composites 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% ZrB2 matrix reveals that the wear surface smoothness of the AMMC is significantly improved as compared to the Al8011 matrix alloys.

Abstract Surface Topography: Metrology and Properties (STMP) is reaching its 10th Birthday soon and this paper looks at the inception of the journal and the goals set in the mid 2010s and will look back at what it has published in the most highly cited areas and detail future initiatives to serve the readership. STMP publishes the latest physics, chemistry, life science, materials science and engineering research on applied, functional surfaces. It has published ground-breaking work on surface design, measurement, instrumentation, manufacturing, functionality and modelling as well as cross-disciplinary work on surface and interface engineering across an array of different applications. It is the home of papers from the biannual international conference on Metrology and Properties of Surfaces series. The journal was awarded it’s first impact factor in 2017 and has a current value of 2.038 (2020) and is now working to improve on this. A new initiative for 2021 is to offer a collection of papers from emerging leaders within the scope of the journal.
