摘要：

All precipitate morphologies in Mg-8.8%Hg-8%Ga alloy for a range of aging temperatures are investigated in detail using SEM, TEM and OM. The results show that Mg21Ga5Hg3 are the dominant precipitate in Mg-8.8%Hg-8%Ga alloy. Mg21Ga5Hg3 phase precipitate in dispersed particles. There are few papers focuses on the relationship between the aging behavior and the electrochemical and corrosion properties in Mg-8.8%Hg-8%Ga alloy. This study elaborates on the morphological evolution of Mg21Ga5Hg3 precipitates as a function of aging time and temperature and investigates the associated second phase morphology-electrochemical and corrosion response. The corrosion behavior of the Mg-8.8%Hg-8%Ga alloy is also discussed. (C) 2012 Elsevier Ltd. All rights reserved.
