英文摘要	The corrosion behavior and mechanical property of Mg-7Y-x Nd (x = 0.5, 1.0, 1.5 wt%) alloys were investigated. The microstructure and precipitations of Mg-7Y-x Nd alloys were studied by scanning electron microscopy, energy-dispersive spectrometry and X-ray Diffraction. The quantities of the Mg-12 (Y, Nd) phase increased, whereas that of the Mg-24 (Y, Nd) 5 phase decreased with increasing Nd-content. The weight loss rate decreased from 17.5020 mg cm(-2) d(-1) (36.7542 mm y(-1)) to 9.3744 mg cm(-2) d(-1) (19.6862 mm y(-1)). The electrochemical measurement also demonstrated the similar tendency. The loss in mechanical properties after corrosion reaction followed the order Mg-7Y-0.5Nd > Mg7Y- 1.0Nd > Mg-7Y-1.5Nd. The precipitations played dual roles in the corrosion resistance that depended on type and distribution. (c) 2018 Published by Elsevier B. V. on behalf of Chongqing University.
