Abstract:
An attempt was made to compare the effect of thickness on the energy absorbed values and modes of failures of the Charpy Impact Test Specimens made from some High Strength Steels for Aerospace Applications. The values obtained were also compared with mild steel. The Impact Energy value was found to be in the range 65-100 ft-lb using standard heat treatment procedures. The quenching media employed were oil, water and air. It was found that samples quenched either in oil or water gave higher impact values than those quenched in air. When thickness was increased beyond 10 mm. the impact energy attained a minimum value thus confirming that such specimens behave in a similar way as if they were tested under plane strain condition.
