Investigation of structure, mechanical properties and crystallization of aluminum alloys containing aluminum oxide nanoparticles

Abstract

A357 and 6082 aluminum alloys strengthened by aluminum nitride nanoparticles were obtained. The process of crystallization of the A357-0.5 wt% Al2O3 and 6082-0.5 wt% Al2O3 alloys was studied under conditions of varying the cooling rate. The A357 and 6082 aluminum alloy structure and hardness were analyzed for the Al2O3 content from 0 to 1 wt%.
