The effect of fast-neutron irradiation on the J IC fracture toughness of Alloy 718 plate and
weld was characterized at 427° C. Two heat treatments were employed: the ASTM B637 …

Alloy 718 is a nickel-base superalloy whose strength derives from γ′(Ni3 (Al, Ti)) and γ
″(Ni3Nb) precipitates. The evolution of the precipitates in alloy 718 irradiated with argon …

In this study, the capability of heavy-ion irradiation to emulate neutron irradiation was
demonstrated on an austenitic 21Cr32Ni type ternary model alloy. The model alloy used in …

Thirteen austenitic stainless steels, nickel-base alloys, and ferritic alloys were irradiated
using 2 MeV protons at 360° C to a damage level of 2.5 displacements per atom (dpa) …

Inconel 718 samples were irradiated with 50 keV He+ ions at 300° C to 0.4, 4 and 40 dpa.
