Radiation-Induced Phase Instabilities and Their Effects on Hardening and Solute Segregation in Precipitation-Strengthened Alloy 718 Larry E. Thomas, Bulent Hakan Sencer and Stephen M. Bruemmer Pacific Northwest National Laboratory Richland, WA 99352 ABSTRACT A classic example of radiation-induced phase instability and degraded mechanical properties occurs in γ’-γ"-strengthened alloy 718. During irradiation with neutrons or protons at ~ 30 to 288°C, the Ni3Nb γ" particles disappear after low doses. The γ' (present only in the matrix) also disappears after
