Solid solution ceramics of transition-metal carbides possess higher hardness and better oxidation resistance in comparison with monolithic transition-metal carbides. In this communication, (Ti, Zr)C solid solution nanofibers were successfully fabricated through electrospinning using polymeric precursors. The effect of n (Ti)/n (Zr) on the microstructure of nanofibers was investigated. Complete solid solutions of (Ti0.8Zr0.2)C and (Ti0.75Zr0.25)C were formed at 1600 degrees C when the value of n (Ti)/n (Zr) equal to 4 and 3, respectively. With a decrease inn (Ti)/n (Zr) to 2, Ti-rich and Zr-rich phases appear. The oxidation resistance of the fabricated nanofibers was tested by a non-isothermal method. The oxidation temperature of (Ti, Zr)C solid solution nanofibers is improved compared to TiC nanofibers.
