3- Refractory metals – Vanadium alloys (4/7)Mechanical properties : V is ductile ![Chung 1996] [Gentzbittel 2012]DBTT = -200°C• low DBTT (-200°C) compared to ODS steels (~-100°C at best)• limited primany and secondary creep• ductile behavior (≠ ODS)Marion LE FLEM, Advanced Materials for Fuel Cladding in Sodium Fast Reactors 18
3- Refractory metals – Vanadium alloys (5/7)Mechanical properties : V is ductile ! Even after irradiation• Embrittlement at low irradiation temperature but recovery above ~400°C• Basically, total recovery at 0.3×Tm = 650°C• Detrimental effet of O and high Cr (more pronounced embrittlement)Marion LE FLEM, Advanced Materials for Fuel Cladding in Sodium Fast Reactors 19
