The method of LMTO Green's functions has been used to calculate the electronic structure of the B2 phase of intermetallic compound NiTi, and of Ni impurities at the Ti site, and Fe and Cu at the Ni site. Using a linear approximation for the dependence of the total density of states of the dilute alloy on concentration, the electronic structure of compounds Ni50Ti50, Ti50Ni45Fe5 and Ti50Ni40Cu10 is determined. It is concluded that the structural properties of NiTi change with deviation from equiatomic composition, and when iron and copper are added.
