Title: In Situ High-Cycle Fatigue Reveals Importance of Grain Boundary Structure in Nanocrystalline Cu-Zr

Abstract

The radiation tolerance of metals can be improved through the incorporation of surfacesand interfaces within the material. Nanocrystalline metals are especially attractive due to theirlarge interfacial volume fraction in the form of grain boundaries, but grain growth duringirradiation usually degrades any improvement in radiation tolerance. Therefore, methods to limitgrain growth and simultaneously improve the radiation tolerance of nanocrystalline metals areneeded. Amorphous intergranular films are unique grain boundary structures that are predicted tohave improved sink efficiencies compared to traditional ordered grain boundaries due to theirincreased thickness and amorphous structure. In addition, amorphous intergranular films havebeen shown to improve the grain size stability of nanocrystalline alloys since they arethermodynamically-preferred at very high temperatures and also can kinetically slow migrationdue to the interface being heavily doped. In this study, ball milled nanocrystalline Cu-Zr alloysare heat treated to either have only ordered grain boundaries or to contain amorphous intergranularfilms distributed throughout the grain boundary network, and are then subjected to in situtransmission electron microscopy irradiation and ex situ bulk irradiation. Differences in defectdensity and grain growth due to grain boundary structural transitions are then investigated. Whenamorphous intergranular films are incorporated within the material, not only is the net sinkefficiency of the entire grain boundarymore » network increased, but grain growth is also limited, leadingto nanocrystalline alloys with improved radiation tolerance.« less
