Stress Corrosion Cracking of Zirconium Cladding Tubes: III. Effect of the Alloy Strength

摘要

The stress corrosion cracking resistance of zirconium T110, E635, and Zirkaloi-4 alloys of different strengths provided by different mechanisms of hardening (solid solution, precipitation, and strain hardening) is studied. It was shown that the stress corrosion resistance of the tubes decreases when the alloy strength increases, in particular, at strain hardening.
