Abstract Aiming to develop a possible approach to precisely control the degradation rate of long period stacking order (LPSO) structured Mg-Zn-Y-Zr alloys in NaCl solution, this work investigates the degradation behavior and the relation between degradation rate and two key microstructural parameters, namely grain size and volume fraction of LPSO phase. Experimental results indicate the numerical relation between degradation rate and these two microstructural parameters. Mathematical processing of interpolation, regression and data fitting is used to establish the quantitative relations among volume fraction of LPSO phase, grain size and degradation rate.
