摘要
The corrosion resistances of some Zr - Sn - Nb - Fe - Cr alloys have been investigated at 400 degrees C/10.3 MPa steam and 360 degrees C/18.6 MPa lithium hydroxide solution with 7x10(-5) Li, respectively. The structure and composition of the second phases in the alloys were determined using TEM and EDAX. The results show that the alloy with low Nb content (0.2 wt%) has superior corrosion resis tance in both media. The alloy with high Nh content (1.0wt%) and low Fe/Cr ratio has worse corrosion resistance in both media. The alloy with high Nh content and high Fe/Cr ratio has better corrosion. resistance in steam and worse corrosion resistance in lithium hydroxide solution. The different performances of the alloy with low Nh content and low Fe/Cr ratio in various media result from the structures and compositions of the second phases.
