Microstructural Characteristics and Mechanical Properties of Cast Mg-3Nd-3Gd-xZn-0.5Zr Alloys
文献摘要：
The microstructure,aging behavior and mechanical properties of cast Mg-3Nd-3Gd-xZn-0.5Zr(x=0,0.5,0.8,1 wt％)alloys are investigated in this work.Zn-Zr particles with different morphologies form during solution treatment due to the additions of Zn.As the Zn content increases,the number density of Zn-Zr particles also increases.Microstructural comparisons of peak-aged studied alloys indicate that varying Zn additions could profoundly influence the competitive precipitation behavior.In the peak-aged Zn-free alloy,β"phases are the key strengthening precipitates.When 0.5 wt％Zn is added,besides β"precipitates,additional fine β1 precipitates form.With the addition of 0.8 wt％Zn,the peak-aged 0.8Zn alloy is characterized by predominantly prismatic β1 and scanty basal precipitate distributions.The enhanced precipitation of β1 should be primarily attributable to the presence of increased Zn-Zr dispersoids.When Zn content further increases to 1 wt％,the precipitation of basal precipitates is markedly enhanced.Basal precipitates and β1 phases are the key strength-ening precipitates in the peak-aged 1Zn alloy.Tensile tests reveal that the relatively best tensile properties are achieved in the peak-aged alloy with 0.5 wt％Zn addition,whose yield strength,ultimate tensile strength and elongation are 179 MPa,301 MPa and 5.3％,respectively.
