Helium bubble microstructure in stainless steel implanted under various conditions

The helium bubble microstructure, i.e. bubble size distribution and bubble density, has been investigated for specimens of AISI 316 SS (s.a. + 24 h at 1073 K) implanted with helium under different conditions by varying parameters like helium concentration, C He, helium implantation rate, C He, and a...

Description
Summary:The helium bubble microstructure, i.e. bubble size distribution and bubble density, has been investigated for specimens of AISI 316 SS (s.a. + 24 h at 1073 K) implanted with helium under different conditions by varying parameters like helium concentration, C He, helium implantation rate, C He, and applied stress, σ. The mean bubble radius, \ ̄ gg and the bubble number density, ρ, have been determined for each of the different microstructural regions, i.e. within the grains (matrix), grain boundaries, and grain boundary precipitates, respectively. The results may be related to the corresponding creep properties of samples with identical treatment.
