摘要: The high strain shear rate behaviour of Inconel 690 alloy was investigated by using the split Hopkinson torsional bar. rates were tested at 900 s−1, 1900 s−1, and 2600 s−1 temperatures −100°C, 25°C, 300°C, respectively. It found that dynamic sensitive to temperature. fracture increased with increasing In addition, sensitivity but decreased Finally, surfaces contain dimple-like features, dimple density
