Abstract: An investigation was made on the possibility of using Ni-x phase diagrams to judge the sym- bol and degree of segregation of alloying element x in cast nickel-base superalloys.The pre- diction coincides with the experimental data.

Key words: cast nickel-base superalloy, segregation, liquidus slope
