Abstract

The effect of Mn on the solidification microstructure, tensile properties and corrosion behavior of Mg_95.5Y₃Cu_1.5 alloy was investigated. The results show that with the increase of Mn content, the primary α-Mg phase in the alloy is gradually refined, and it also changes from dendritic to equiaxed dendritic morphology, while the morphology and volume fraction of LPSO phase do not change significantly. The addition of Mn improves the tensile properties of the alloy. When the Mn content is 0.9% (atom fraction) the yield strength, ultimate tensile strength and elongation are increased by 20.7%, 17.6% and 41.0% respectively compared with the alloy without Mn addition. In addition, the corrosion performance of the alloy is also improved. With the increase of Mn content, the volume of hydrogen evolution rate, mass loss rate and corrosion current density of the alloys gradually decrease, and the corrosion potential of the alloys, meanwhile, gradually moves towards positive direction.

Key words: metallic materials Mg-Y-Cu alloy microstructure tensile property corrosion behavior Mn content
