  • Structure of the Ni-base superalloy IN 713C after continuous casting
    Zupanič, Franc ; Bončina, Tonica ; Križman, Alojz
    In this work a Ni-base superalloy IN 713C was continuosly cast in the form of rods with a circular cross section under protective argon atmosphere using a vertical continuous caster. The structure of ... rods cast at different casting parameters was investigated using different microstructural characterisation techniques. It was found that the superalloy IN 713C could be continuosly cast over a wide range of casting parameters. The continuusly cast rods possessed a clean surface and excellent internal integrity without nonmetallic inclusions and porosity. The microstricture consisten of ▫$\gamma$▫-grains, interdendritic ▫$\gamma$▫ /MC eutectic and coherent ▫$\gamma^,$▫ precipitates distributed uniformly within the ▫$\gamma$▫ -matrix. The size, distribution, morphology and orientation of microstructural constituents depended strongly on local solidification conditions, which were greatly influenced by the nozzle/mould set up and the alternating drawing mode of continuous casting. The results of the work strongly suggest that IN 713C could also be continuously cast using large-scale industrial equipment.
