Abstract An investigation was made on the Possibility of using Ni-x binary diagram to ju-dge the positive, negative segregation or almost no segregation and degree of segregation of alloyingelement x in cast Ni-base superalloys. The prejudicat coincides with the experimental data.

Key words: cast Ni-base superalloy segregation liquidus
