Effect of Solution Temperature on Microstructure and Properties of Mg-2Zn-0.5Zr-1.5Dy Alloy

Abstract:

The purpose of this paper is to investigate the effect of solution temperature on the microstructure and properties of Mg-2Zn-0.5Zr-1.5Dy alloy was studied by optical microscopy (OM), immersion experiment and electrochemical experiment. The results show that the alloy has the best comprehensive properties when the solution temperature is 470°C. The minimum average grain size was 97 μm. The I_corr and E_b of as-cast alloy are-3.55 μA/cm² and-1.27 V, respectively, according to polarization curve fitting. With the increase of solution temperature, the value of I_corr first decreases and then increases, and E_b first increases and then decreases. After solution treatment at 470°C, I_corr and E_b are 1.41 μA/cm² and-1.14 V, respectively.
