Titanium Carbide Effects on the Fracture of Inconel 100—A Case Study

Carbides and borides appear as minor phases in Inconel 100, although the carbon content (0.18%) is relatively high comparison to other nickel-base superalloys. The material properties of this alloy depend on a number interrelated microstructural parameters, including volume fraction γ' γ, grain size, elemental distribution, precipitation carbides borides. This study presents characterization failure analysis 100 samples loaded fracture at 760℃ an examination their fractography. Chemical analysis, optical metallography, SEM EDS were used for unusual areas that found samples. thermodynamic stability TiC led conclusion possibility creating very large, stable mono carbides, especially carbide, during production process reason short time obtained work.
