摘要	The precipitation of nano-scaled M23C6 carbide at intragranular regions (especially in dendritic core regions) has been systematically investigated in a directionally solidified Ni-base superalloy. The crystallographic orientation relationship between the M23C6 phase and the gamma matrix phase was found to be (100)(M23C6)//(100)(gamma), [100](M23C6)//[100](gamma). Additionally, M23C6 carbide was very stable during creep and long-term thermal exposure, which makes the fine M23C6 carbide an effective strengthening phase in gamma matrix. (C) 2009 Elsevier Inc.
