Abstract

The influence of temperature, strain rate history, and shock-wave prestraining on the mechanical behavior of Armco-iron (Fe) is presented. Shock-wave prestraining of iron above the polymorphic α-ε transition is seen to result in significant changes in the stress-strain response of Fe. The increase in the constitutive response of Fe is seen to correspond to an increase in hardness in the preshocked Fe. A high degree of correlation in the experimental results independently obtained in Russia and USA is presented. The observed mechanical property effects in preshocked Fe are correlated to the microstructure evolution in iron following explosive prestraining.
