Because Nb accelerates the uniform distribution of MC phase and the grain refinement,as well as,increases the amount and stability of γ-phase,the tensile strength,ductility,stress rupture life and fatigue limit of Fe-30Ni-13Cr-1.2W-1.5Mo-2.5Ti-0.4AI superalloy at 650℃ can be improved with increase of Nb content up to 1.22 wt-%.The precipitation of small Laves phase particles dispersed along grain boundaries may be favourable to combined properties of the superalloy containing 1.22 wt-% *** will be worsened only that the pre- cipitation of Laves phase particles'dispersed along grain boundaries may be favourable for combined properties of the superalloy containing 1.22 wt-% *** will be worsened only that the precipitation of Laves phase is too more because of too high Nb content existhing.

China Welding 1994年第2期3卷 146-150页

作者： ZHENG Benying (Dongfang Electrical Machinery works, Sichuan Deyang (618000)

Hydroelectric power equipment consists of a hydro-turbine and a hydrogenerator whose weldments have the features of complicated construction and large bulk as well as some parts operating under water. With the increase of unit rating of the hydroelectric power equipment, the application field of high strength steel and dissimilar steel has been enlarged. What to be introduced in this paper is the development of the welding technology of large hydroelectric generating equipment in China since the 1970s, and the development orientation of its welding construction and procedure in the future.

The distinct images of intragranular VC were observed on TEM in superalloy GH36 underwent normal heat treatment and prolonged *** size of VC particles were meas- ured by means of Moire pattern,and the misfit between VC and austenite was also calculated. The M23C6 enveloped in VC shell was also observed in the prolonged-aged *** coherent relation between intragranular M_(23)C_6 twins and austenite as well as its coherent in- terface were also studied.
