摘要Fatigue tests were performed on two types of [(1) over bar 34] iso-axial copper bicrystals for studying the grain boundary (GB) effects on the cyclic deformation and fatigue cracking behavior and the corresponding mechanism in copper bicrystals. One bicrystal contains a perpendicular GB and the other contains a tilting one with respect to the loading axis. Both the grain boundaries are nearly 180 degrees rotated. It was shown that both the perpendicular and tilting grain boundaries have little effect on the cyclic hardening and saturation behavior of the bicrystals, but show strong effects on the slip deformation and fatigue cracking behavior. The microcracks were found to prefer to nucleate and propagate at the GB, leading to intergranular cracking. However, the crack nucleation behavior was found to be different for the above two iso-axial copper bicrystals. Two types of intergranular fatigue cracking mechanisms were proposed based on the specimen geometry with respect to the dominant slip system and the GB orientation. (C) 1998 Elsevier Science Ltd.
