Microstructures,mechanical properties and degradability of Mg-2Gd-0.5(Cu/Ni)alloys:A comparison study
文献摘要：
Low alloying Mg-2Gd-0.5(Cu/Ni)alloys for sealing tools in the oil and gas industry were prepared.The differences in the effects of minor Cu and Ni additions on microstructures and properties of the Mg-2Gd alloy were compared.The results showed that adding Ni was more effective than adding Cu in re-fining grain sizes,strengthening the basal fiber texture,and promoting the formation of LPSO phases,resulting in higher strength.The tensile yield strength/elongation of the Mg-2Gd-0.5Cu alloy,Mg-2Gd-0.25Cu-0.25Ni alloy,and Mg-2Gd-0.5Ni alloy was 146 MPa/23.7％,175 MPa/23.1％,and 248 MPa/18.2％,re-spectively.The decreased elongation was attributed to the basal fiber texture and the presence of coarse LPSO phases.In terms of the corrosion rate in 3.5 wt.％NaCl solution,it rose from 112 mm y-1 for the Mg-2Gd-0.5Cu alloy to 269 mm y-1 for the Mg-2Gd-0.25Cu-0.25Ni alloy and 490 mm y1 for the Mg-2Gd-0.5Ni alloy,indicating that the addition of Ni instead of Cu showed a more significant promoting effect on the degradability of Mg alloys,which was related to more refined grains,the stronger basal fiber texture,and a larger amount of LPSO phases.
