文摘In this paper,the microstructure and hydrogen embrittlement(HE) susceptibility of an Fe-Ni-Co based superalloy with different contents of trace elements,P and Mn,have been investigated.The results indicated that by lowering the contents of trace elements P and Mn,the size and distribution of γ' become more homogeneous,and the precipitation of stable phase η can be retarded to longer ageing time.As a result,the hydrogen resistant properties of the alloy are obviously improved.
