Influence of irradiation temperature on void swelling in NiCoFeCrMn and NiCoFeCrPd
Abstract
Here, using ion irradiation and transmission electron microscopy, temperature dependent void swelling and dislocation loop evolution in equiatomic NiCoFeCrMn and NiCoFeCrPd high entropy alloys were investigated. Voids were observed in all tested conditions. An order higher of swelling was observed in both HEAs as temperature increased from 420 to 580 °C. Alloying with Pd was found to have a stronger suppression effect on void and dislocation loop growth than alloying with Mn. Possible contributions to the swelling resistance were explored, including localized lattice distortion and higher defect migration barrier in NiCoFeCrPd. Additionally, no phase decomposition was observed in either alloy.
