Microstructures, mechanical properties, and oxidation behavior of in-situ ultra-fine duplex carbides reinforced Ni-based superalloy composites
Source abstract
Abstract
A Ni-based superalloy composite (FTSC) was successfully prepared by spark plasma sintering with Ti 3SiC 2 (15 vol%) and FGH97 alloy powders as precursors. During sintering, the weakly bonded Si layers de-intercalate from Ti 3SiC 2 and the remaining TiC is eroded by the elements of the matrix, which promoted in-situ precipitation of MC and M 6 C carbides. MC with core-shell structure builds up a semi-coherent interface with the alloy matrix: ( 1 ¯ 1 1 ¯ ) γ/γ`‖ ( 1 1 ¯ 1 ) MC with [110] γ/γ`‖[110] MC . The Zener pinning effect of ultra-fine duplex carbides results in refinement of alloy grains and notably improvement in mechanical strength. Comparing to the alloy FGH97, the composite FTSC possesses 55% higher microhardness, 100% higher compressive yield strength and 92% higher flexural strength. On the other hand, the refined grains ensured fast formation of a protective alumina scale at surface, which provides high oxidation resistance for the composite.
