Abstract
- Ti 3 SiC 2 is of interest due to its unique dual nature reminiscent of both brittle ceramics and ductile metals at ambient conditions. In this work, plate-impact experiments have been performed to study the dynamic behavior of Ti 3 SiC 2 under shock compression up to 112 GPa by using laser velocity interferometer and electric pin techniques. Hugoniot elastic limits (HEL), spall strength, and Hugoniot equations of state have been obtained based on measured particle velocity profiles and shock wave velocities. The ratio of spall strength to HEL for Ti 3 SiC 2 is larger than brittle ceramics but smaller than metals. This result indicates that the dual nature of Ti 3 SiC 2 remains at least up to 10 GPa. On the other hand, the linearity of the Hugoniot equation of state, D = 6.9 0 1 (22) + 1.153 (53) u p , suggests that the initial structure of Ti 3 SiC 2 should be stable up to 112 GPa, in contrast to the result reported by Jordan et al. [J. Appl. Phys., 93 (2003) 9639]. [ABSTRACT FROM AUTHOR]
