In this work，the superalloy employed is MM247（Ni-8.2Cr-9.2Co-0.5Mo-9.4W-5.6Al-3.2Ta-0.7Ti-0.08C-1.1Hf，wt.%），which is a multicomponent alloy.In order to investigate the solidification process，the proposed model is effective for using the equivalent binary alloy model to simplify the real alloy.The solidification of MM247 superalloy could be regarded as a single phase（γ）solidification process.Therefore，the equivalent binary Ni-X alloy was used to simulate the DS process of MM247 superalloy.Some equivalent thermophysical parameters of the Ni-X alloy were calculated by using commercial PANDAT software.However，due to the limitation of PANDAT software and issues with robustness，an optimized table-look-up technique is adopted to provide access to the data needed in the simulation.Some key thermophysical parameters of the Ni-X alloy are given in Table 1.
