摘要	A well-dispersed (Ti,Nb,W)C particulate reinforced nickel-base superalloy was prepared via super-high temperature (above 2123 K) treatment of melt. Scanning electron microscope (SEM) observation and energy dispersive X-ray spectroscopy (EDS) results show that most of the (Ti,Nb,W)C particles have a carbonitride core. Gas analysis shows that nitrogen content in the alloy with super-high temperature treatment of melt is much higher than that in the conventional cast superalloy. The welldispersed (Ti,Nb,W)C particles could be attributed that nitrogen combines with Ti in the alloy melt to produce TiN, which acts as the nucleator to form (Ti,Nb,W)C. This work provided a new way to prepare the TiC particulate strengthened composites. (C) 2003 Elsevier Science B.V. All rights reserved.
