| 英文摘要 | Nickel-based alloy Inconel 690 (hereinafter called alloy 690) is currently replacing alloy 600 as steam generator tubes in pressurized water nuclear reactors, owing to its excellent resistance to intergranular stress corrosion cracking (IGSCC) and good mechanical properties. The carbide precipitation is a major microstructural characteristic during heat treatment of stainless steels and nickel-based alloys. The carbide precipitation and chromium depletion in the grain boundary of alloy 690 were investigated. The grain size and carbide of alloy 690 with 0.001% and 0.03% (mass fraction) nitrogen contents were observed and analyzed. The extent of chromium depletion in the vicinity of grain boundaries was quantitatively determined as a function of thermal treatment time. The solution treatment of the samples was at 1080 degrees C for 10 min, and then the samples were thermally treated at 715 degrees C for 1 similar to 25 h. The results show that the nitrogen addition decreases the intergranular carbide density and the average carbide length but increases its distance. The level of chromium in the depleted regions in alloy 690 with 0.03%N is higher than that with 0.001%N. This is attributed to the beneficial role of nitrogen addition against grain growth and sensitization. |
