Experimental Liquidus Surface Projection and Isothermal Section at 1000 °C of the V-Ni-C System

Abstract

Twenty-three V-Ni-C alloys were produced and analysed in the as-cast condition, as well as after annealing at 1000°C for 1000 h. The phases were identified using SEM-EDX and XRD. The extensions of the binary phases were determined. The liquidus surface projection was derived from the overall compositions, primary phases and the solidification sequences. Four invariant reactions on solidification were found. The isothermal section at 1000°C was also derived, which included the * Ni 2 V 4 C ternary phase.

“…In the case of the samples prepared with Ni paint and resin, the absence of other phases ( Figure 4 ) is in agreement with the Ni-Cu binary phase diagram [ 46 ], where the formation of alloys between Ni and Cu just takes place at higher temperatures ( ) while at lower temperatures, a solid solution between Cu and Ni can exist. The absence of reactions between the Ni and C (Ni just presents a small solubility into graphite [ 47 ]) can also explain the inexistence of other compounds at their interface.…”
