Tritium Properties and Interactions with Material / Proceedings of the Third Topical Meeting on Tritium Technology in Fission, Fusion and Isotopic Applications (Toronto, Ontario, Canada, May 1-6, 1988) / dx.doi.org/10.13182/FST88-A25206

Recent aging studies performed on dilute and concentrated metal tritides are reviewed. Also, new results concerning property changes in metal tritides as a function of aging time are included. We mainly report on TEM studies of aged tritides, the swelling behavior, hardness measurements, selected mechanical properties, acoustic emission and tritium diffusion experiments. Models of the microstructure of aged tritides are also reported. Density measurements on tritides are discussed.
