Abstract

Abstract

The precipitation phases present in argon-atomized FGH95 superalloy powders were studied by X-ray diffraction, transmission electron microscopy and X-ray energy dispersive spectra techniques.
The major precipitate Phase in the interior of the powder particles is identified as MC-type carbides containing Nb and Ti with some Cr,Ni, Mo and W.The morphology of MC-type carbides may be related to the composition of the alloy and the condition of its solidification.Minor Phases,such as Laves phase, primary γ' phase and boride phase are also present.
