    Abstract

    The effect of shock strengthening on impact properties of Type 316 stainless steel at temperatures ranging from room temperature to 650°C (1202°F) was established by utilizing the instrumented Charpy impact test. It was found that the total impact energy absorbed progressively decreases with increasing shocking pressure.

    The dynamic yield strength (σdy) was increased by increasing the shocking pressures for all testing temperatures. This trend is expected because the static yield strength (σsy) was also found to increase with increasing shocking pressure. However, the ratio of dynamic-yield to static-yield strengths (measure of strain-rate sensitivity) was found to decrease with increasing shocking pressure.
