| 제목 | Compression Deformation Properties of TiC-Mo Composites at High Temperature |
| 초록 | TiC is expected to have the highest specific strength because it has the lowest density among the transition metal carbides, and hence it is most attractive for high temperature applications. Monocarbides of group Ⅳa, Ⅴa and Ⅵ a transition metals have very high melting points above 2900 K, extremely high hardness and excellent high temperature strengths, as well as thermal and electrical conductivities as good as those of metals. Many investigations on the mechanical behavior of TiC have been reported, but its high temperature deformation has not yet been well established. Deformation properties of TiC-Mo composite have been investigated in compression test at high temperatures from room temperature to 2053 K and strain rates from 3.9×10-5/s to 4.9×10-3/s. It is found that this material shows excellent high temperature strength as well as appreciable room temperature toughness, suggesting that the material is a good candidate for high temperature application as structure material. From the observed high temperature deformation behavior, it is argued that the excellent high temperature strength is due to the constraining of deformation in the Mo phase by thin TiC which are considerably stronger than bulk TiC.
