High-Temperature Compressive Response of SiC<sub>p</sub>/6092Al Composites under a Wide Range of Strain Rates

The high-temperature dynamic compressive properties of a 30 vol.% SiC<sub>p</sub>/6092Al composite, fabricated using powder metallurgy, were experimentally investigated using the split Hopkinson pressure bar system with an electric furnace. Three different ambient temperatures, namely, r...
