A review of nanoparticle effects on aluminum alloys and weldability

Abstract

The ongoing trend for reducing energy consumption and emissions has led scientists to investigate new methodologies for improving lightweight materials in order to make them more qualified for different types of struc tural engineering applications The most common lightweight materials used in structural assembly are high-strength aluminum alloys that show certain difficulties when welded and require special techniques for achieving homog enous crack-free welded joints. Nanoparticle reinforcement of aluminum al loys is a promising methodology for phase-controlling solidification of welded joints. The microstructure and properties of these welds are determined by the nanoparticles introduced and the welding parameters used during the welding process. The aim of this paper is to go over recent publications on nanoparti cle reinforcements of aluminum alloys and their use in welding production. It summarizes the effect of different nanoparticle reinforcements on grains and properties of welded joints and discusses further development and application of hybrid nanostructured aluminum alloys.
