Stress-strain properties and micro-structural change in metal deformed at strain rates of upto 10^5 per second.

5 per second. Comparative studies showed that copper was more strain ratesensitive than aluminium and steel used in the present investigation.There were no marked differences observed in the microstructures of the structural steel specimen deformed quasi-statically and dynamically at -30°C, room temperature and at 235 C. There was also no distinguishable micro-structural change observed in the structure of aluminium specimen deformed at low and high strain rates but mechanical twinning was observed in the microstructure of copper specimens deformed at high strain rates.
