Abstract
FGH 97 alloy (FG) and its composite with TiC addition (FT) were prepared by spark plasma sintering. The TiC particles were dissolved into the alloy matrix during ball milling, but precipitated out in-situ as MC solid solution with semi-coherent interface after sintering, leading to a homogeneous and fine microstructure. After exposure to 900 °C for 300 h, its grain size grew by only 31%. The fine microstructure promoted selective oxidation of Al and ensured high oxidation resistance of the composite FT. The precipitated carbides increased oxidation resistance of FT and endows its oxide scale with self-healing ability for long-term oxidation.
