WebA self-consistent thermodynamic description for the Fe-Nb-Ti-C-N quinary system has been developed. Because many different descriptions were already available for most of the sub-binary and ternary systems, a selection among several parameter sets had to be made. This was done for the Fe-Ti, Ti-C, and Ti-N systems considering experimental ...
