  • Quasi-static and dynamic compression experiments of unannealed Ta-10W alloy specimen are implemented by MTS and split Hopkinson pressure bar equipments. Quasi-static compression yield strength is gained. In addition, the stress-strain history and dynamic compression yield strength are obtained when strain rate ranges from 700 s-1 to 3 100 s-1. The experiment results indicate that unannealed Ta-10W is preferably flexile. There is no crack on the surfaces of specimen after experiments. The quasi-static and dynamic compression strength of unannealed Ta-10W alloy is quite large. Quasi-static compression yield strength is about 930 MPa, and the dynamic compression yield strength is over 1 GPa. Dynamic compression yield strength of Ta-10W is dependent on strain rate, and it grows from 1.0 GPa to 1.3 GPa when strain rate increases from 700 s-1 to 3 100 s-1.
