% ta were experimentally investigated by DTA, and the phase transformation sequences of the alloys Fe-2
93C-0
1Ta and Fe-2
31C-0
5Ta were analyzed
A thermodynamic calculation of this system was carried out using CALPHAD technique
The results show that the thermodynamically calculated results agree well with the experimental data
There are four nonvariant reactions in the liquidus projection of Fe-C-Ta system in the Fe-rich corner: Liquid+bcc ↔fcc+TaC
