Title: Irradiation induced creep in nanocrystalline high entropy alloys

Abstract

Irradiation induced creep (IIC) compliance in NiCoFeCrMn high entropy alloys is measured as a function of grain size (30 < x < 80 nm) and temperature (23° C- 500° C). For 2.6 MeV Ag3+ irradiation at a dose rate of 1.5x10-3 dpa-1s-1 the transition from the recombination to sink limited regimes occurs at ~ 100 °C. In the sink-limited regime, the IIC compliance scales inversely with grain size, consistent with a recently proposed model for grain boundary IIC [1]. Thermal creep rate is also measured; it does not become comparable to the IIC rate, however, until ~ 650 oC. The results are discussed in context of defect kinetics in irradiated HEA systems.
