Abstract  The calculation of electronic structure of γ'-Ni_3 Al phase with orwithout Mg and W by the Recusion and LCAO mehtods clarified that Mg and Watoms lose their outer electrons partially after they entered γ'-Ni_3 Al. It causes thereduction of the radii of atoms (so it is preferable for Mg atom to enter γ' phase bythe substitution). Thus, the interaction between Mg and γ'-phase matrix may bestrengthened and a more stable structure of γ'-phase may be formed while Mg andW entered simultaneously γ'-Ni_3 Al.
Key words:  superalloy      Ni_3Al_1      electronic structure      Mg alloying
