Formation of Adiabatic Shear Bands During Upsetting of 18-4-1 Alloy Steel at High Strain Rates
Optical Metallographic studies on the specimens deformed at different temperatures (Room temperature to 900°C) and mean strain rates of 0.015, 0.6, 11.0 and 470 s−1 using compression testing machine, double action hydraulic press, friction screw press and high velocity gravity drop hammer respectively were carried out. The specimens were heated to the required temperatures by means of a tubular furnace included in the tool set-up itself.
