Effects of nano-Al2O3 on the compression flow curve of AZ11 magnesium alloy at room temperature
Journal Title: Journal of Science and today’s world - Year 2015, Vol 4, Issue 10
Abstract
In this study, we performed compression testing on an AZ11 magnesium alloy with and without alumina nano particles as an additive. The nanoparticles were tested at various sizes (30, 80, and 150 nm) and different percentages by weight (1%, 2% and 4% particle load) at room temperature. Samples were prepared by casting in lowcarbon steel molds and turned to have appropriate size and surface quality. Due to the small radius of the barreling in samples, was ignored. The presence of nano-Al2O3 particulates with a size of 30 nm and 2% volume significantly improved (by 13.44%) the compressive yield strength of AZ11 magnesium alloy. An attempt is made to correlate the effect of the amount and size of Al2O3nanoparticulates on the properties of AZ11 magnesium alloy.
