Abstract

The addition of Cr to (Mo_0.85Nb_0.15)Si₂ crystals significantly improves the thermal stability of the lamellar structure composed of C11_b-MoSi₂ and C40-NbSi₂ phases. Analysis using electron microscopy indicates the segregation of Cr atoms at the C40/C11_b lamellar interface. This leads to a decrease in the lattice misfit strain at the interface and better thermal stability of the lamellae.
