Keywords
  • Thin Foils Of An ‘ Experimental ’ Austenitic Stainless Steel
  • With And Without Dispersions Of Aluminium Oxide Particles
  • Are Irradiated With 1 Mev Electrons In A High Voltage Electron Microscope At 600°C
  • Evidence Of Grain Size Dependent Void Nucleation
  • Void Concentration
  • And Void Volume Swelling Are Presented For Grains In The Size Range 0°45 To 50 μ
  • In Both Undoped And Helium-Doped Samples The Void Nucleation Is Delayed
  • Void Concentration Is Lowered
  • And Void Volume Swelling Is Reduced By Decreasing The Size Of The Grain Under Irradiation
  • The Results Are Discussed In Terms Of A ‘ Defect Depletion ’ Model Based On The Property Of Grai
  • It Is Suggested That Even In The Presence Of Sufficiently Large Amount Of Impurity Gas Atoms
  • A Critical Level Of Vacancy Supersaturation Is Necessary To Produce Critically Sized Vacancy Cluster
  • It Is Concluded That The Presence Of Stable And Small Grains Improves The Damage Resistance Of The M
