The addition of Cr to (Mo0.85Nb0.15)Si2 crystals significantly improves the thermal stability of the lamellar structure composed of C11b-MoSi2 and C40-NbSi2 phases. Analysis using electron microscopy indicates the segregation of Cr atoms at the C40/C11b lamellar interface. This leads to a decrease in the lattice misfit strain at the interface and better thermal stability of the lamellae.
