    A new modification of Dayananda's method was proposed that enables an evaluation of concentration dependence of diffusion matrix elements D(Ni)ij, using one diffusion couple. The procedure is applied to interdiffusion in gamma’-Ni3Al-X (X = Cr, Fe, Nb, Ti) in temperature interval 1173 - 1533 K.

    Byla navržena nová modifikace Dayanandovy mehody, která umožňuje stanovit koncentrační závislost prvků matice D(Ni)ij, za použití jednoho difúzního článku. Tento postup byl aplikován na interdigúzi v gama’-Ni3Al-X (X = Cr, Fe, Nb, Ti) v teplotním intervalu 1173 - 1533 K.
