Influence of Tungsten Nanoparticles on Microstructure and Mechanical Properties of an Al-5%Mg Alloy Produced by Casting

This paper investigates the impact of tungsten nanoparticles on microstructure and mechanical properties Al-5Mg alloy. Tungsten concentrations up to 0.5 wt.% led a slight modification alloy microstructure, grain refinement occurred due inhibition crystal growth along boundaries. Dispersion hardening with made it possible increase ultimate strength by Orowan mechanism simultaneous in plasticity An content 0.8 modify alloy, formation Al12W phase an crystallisation centres. The as well dispersion strengthening nanoparticles, yield strength, tensile ductility
