The effect of ion irradiation on evolution of microstructure and hardening of beryllium with different impurity levels was investigated using TEM and nanoindentation. High purity S-65 nuclear beryllium grade and lower-pure S-200-F structural beryllium grade were implanted by helium ions at temperatures of 50ºC and 200ºC. 11 different energies wer…
