Hydrogen pick-up and corrosion behavior of Ti-alloy (PT-7M) in ammonia water chemistry
- 1. Korea Atomic Energy Research Institute, Taejon (Korea, Republic of)
Description
Ti-based alloys have been considered as candidate materials for steam generator tubes of SMART (System-intergated Modular Advanced ReacTor), due to the excellent corrosion resistance, good mechanical properties, attractive density, high neutron stability and suitable durability characteristics. When the Ti-alloys are exposed to the primary coolant water under high temperature and high pressure in PWRs, some of hydrogen resulting from the reaction of the alloy with water is absorbed into metal, and usually forms hydrides. The hydrides in Ti-alloys are well known to contribute to the loss of ductility in tensile, impact strength, toughness and creep resistance. In this study, long term corrosion and hydrogen pick-up behaviors of PT-7M(Ti-Al-Zr alloy) at 360 .deg. C in ammonia water chemistry were investigated. The corrosion rate constants and hydrogen pick-up were evaluated
