REPORT


3. The proposed mechanism of sensitization in the alloys suggests that during the high temperature exposure, the titanium carbonitrides decompose freeing carbon or carbon and nitrogen into interstitial solid solution. During subsequent heat treating at temperatures -600 ~ results in the precipitation of nearly chromium-free TiC. The lack of chromium in these precipitates prevents the formation of chromium-depleted zones, and the alloys are resistant to intergranular corrosion. 4. a' precipitates form after the intergranular precipitates during heat treating at
