Symposium Radiation Effects in Metals and Ceramics
Presentation Title H-40: Effect of Ordered Helium Bubbles on the Deformation and Fracture Behavior in Zr
Author(s) Liu Simian, Han Weizhong
On-Site Speaker (Planned) Liu Simian
Abstract Scope Radiation-induced helium bubbles are detrimental to the mechanical properties of metals, usually causing severe hardening and embrittlement. In this study, we investigated the effect of ordered helium bubble on plastic deformation and the failure of the α-Zr. Helium bubbles prefer to align along the basal plane in α-Zr. Micro-scale in situ tensile tests revealed that helium bubbles less than 8 nm in size can increase the critical shear stress for the prismatic slip; larger bubbles have a higher resistance. However, once the helium bubbles become larger than 8 nm, a bubble-softening effect appears due to an increase in bubble spacing and porosity. Once the Schmid factor for the basal slip is considerably higher than the prismatic slip, the bubble coalescence along the basal plane becomes the major failure model for helium-irradiated α-Zr, rather than the activating prismatic or pyramidal slip.
