“…As the temperature was raised to 1160 °C, Ni 10 Zr 7 disappeared, and there was a large amount of NiZr and a small amount of Ni 11 Zr 9 in the product. Following the Ni-Zr binary phase diagram [ 23 ], Ni 10 Zr 7 and Ni will form a eutectic liquid at 1150 °C, which exactly corresponds to the endothermic peak at 1146 °C in the DSC curve. When the Ni-Zr mixture was heated to 1200 °C, the product mainly consisted of NiZr, Ni 11 Zr 9 and a small amount of NiZr 2 , in which the content of Ni 11 Zr 9 phase increased obviously.…”

“…When the Ni-Zr mixture was heated to 1200 °C, the product mainly consisted of NiZr, Ni 11 Zr 9 and a small amount of NiZr 2 , in which the content of Ni 11 Zr 9 phase increased obviously. According to the Ni-Zr binary phase diagram [ 23 ], NiZr and Ni will form eutectic liquid phase at 1170 °C. Therefore, it can be deduced that the Ni-Zr eutectic liquid will form after the temperature is gradually raised to 1170 °C, which leads to the endothermic peak at 1181 °C.…”

The reaction mechanism of ZrB2-ZrC formation in a 30% Ni-Zr-B4C system under argon was revealed by using differential scanning calorimetry (DSC), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results indicated that the reaction mechanism in the Ni-Zr-B4C system was complex. Initially, NixZry and NixBy intermetallics were formed via solid-state diffusion reactions between Ni, B4C and Zr. Then, the eutectic reaction between Ni2B and Ni4B3 lead to the formation of Ni-B liquid. The free C atoms dissolved into the Ni-B liquid to form a Ni-B-C ternary liquid, and then part of the Zr powder dissolved into the surrounding Ni-B-C ternary liquid to form Ni-Zr-B-C quaternary liquid. Finally, ZrB2 and ZrC formed and precipitated out of the saturated liquid. The eutectic liquid plays an important role during the formation of ZrB2-ZrC.
