INVESTIGATION ON ALLOYS OF ZIRCONIUM WITH NIOBIUM AND/OR SILICON IN VIEW OF THEIR USE AS SHEATHING MATERIAL IN WATER-COOLED NUCLEAR REACTORS. Euratom Research Assignments. Third Quarterly Report

Technical Report ·
OSTI ID:4036698
The temperature dependence of the solubility of niobium in the mixed crystal of alpha -zirconium was determined. The separation of martensitic platelets in alloys with niobium contents ranging between 7.5 and 17% when they were quenched in water was found to be due to the presence of hydrogen. The comparative corrosion tests in steam were extended. An investigation of the hydrogen absorption of some of the alloys during the corrosion process indicated lower absorption values than those observed for Zircaloy-2. It was found that annealing below the monotectoid range had a particularly favorable influence on the corrosion resistance of the alloys. A study was begun on the variations in length of zirconium alloys subjected to alternating temperature s. (auth)
