| Summary |
The compositions, structures and lattice parameters of the precipitates in two Mo-base and two Nb-base commercial alloys were determined. In general, the precipitates were complex carbides which contained all or nearly all of the alloying constituents in solution. In the case of the Mo-base alloys the compositions could be explained on the basis of both the Mo-Ti-C phase diagram and certain thermodynamic data (free energies of formation). This correlation was not possible for the Nb-base alloys because of the lack of these types of information. In all cases, the experimentally determined structures of the precipitates agreed with the accepted structures. The lattice parameters, on the other hand, deviated from the values for the pure compounds but these deviations could be explained on the basis of one or more alloying elements partially replacing the parent metal in solution. |
