EFFECT OF SHOCK-INDUCED HIGH DYNAMIC PRESSURES ON IRON-BASE ALLOYS
Abstract
The effect of high dynamic presures generated by strong shock waves on the metallrgical properties of selected iron based alloys was investigated. this investigation incuded a sudy of the effects of shock wave duration, repeated shocks on a single test specimen, inreasing shock wave intensity, and post shock heat treatment on the yield and tensile stren ths of H-11 tool steel and 25% nickel steel. As a result of explosive shock hardening, H-11 steel increased in yield strength from 235 ksi in the preshocked condition to 340 ksi in the asshocked (360 ilobrs) condition, while the 25% nickel steel showed yield strength increases from 235 ksi in the austenitized-plusaged condition to 255 ksi in the shocked-plusaged condition. These increases in yield strength were brought about wthout any significant macroscopic plastic deformtion. (Author)
