Effect of C11b-Stabilized Element on Deformation Mode in C40-Type (Nb1-xMox)Si2 (x=00.85) Single Crystals Takayoshi Nakano, Koji Hagihara, and Yukichi Umakoshi Division of Materials and Manufacturing Science, Graduate School of Engineering, Osaka University, 2-1 Yamadaoka, Suita, Osaka, 565-0871, Japan ABSTRACT Plastic deformation behavior and the dominant deformation mode in ternary (Nb1-xMox)Si2 (x=0-0.85) single crystals with the C40 structure were examined focusing on the phase stability between the C40 and C11b structures.
