Misfit analysis in lamellar microstructure in NbSi_2/MoSi_2 duplex crystals

摘要

Recent experimental investigation of additional alloying of pseudobinary (Mo_((1-x))Nb_x)Si_2 disilicides showed surprisingly a similar effect of smaller and larger atoms (chromium and zirconium) on the interface misfit. Nevertheless, it is shown in this short paper that the measured modifications of misfit at the interfaces between the C11_b and C40 lattices in two-phase systems of transition metal disilicides can be in agreement with the measured or calculated values of lattice parameters of pure binary systems.
