Post-irradiation helium blistering in copper, austenitic steels and alloys over the temperature interval 0.65-0.95Tmelt
The specimens of copper, austenitic steel 08Cr16Ni15Mo3Nb and nickel-rich 03Cr20Ni45 alloys were irradiated by a-particles (50 MeV, 0.3...3.6 × 10²¹m⁻²) through the special filter-mask and subjected to following thermal treatment at temperatures up to 0.95 × Tmelt for 1...100 h . The helium behavior...
