After being treated in different ways,Zr-Sn-Nb-Fe alloy specimens are exposed in 0.01mol/L LiOH aqueous solution at 350℃ under 16.8 MPa.The examination of microstructures and second phase particles (SPPs) of these specimens was carded out by high-resolution transmission electron microscopy (HR-TEM).The specimens treated at 800℃ before the final cold roiling have a better corrosion resistance than those treated at 680℃,and the specimens treated at 500℃,after the final cold rolling,have a better corrosion resistance than those treated at 560℃.TEM examination shows that the SPPs existing in the 800℃/500℃ specimen,which has the best corrosion resistance,contains a lot of Nb dement,which results in the reduction of the niobium content in the a-Zr solid solution.
