An Investigation of the Influence of Shock-Wave Profile on the Mechanical and Thermal Responses of Polycrystalline Iron.
Abstract
The purpose of this investigation is to study the influence of the shock-wave profile on the mechanical response of polycrystalline iron. The objective of this Interim Technical Report is to provide information in regard to significant progress made in this study. The three shock-wave parameters associated with the shock-wave profile are peak pressure, duration of peak pressure, and rarefaction rate. It is now evident that the major parameter of importance in developing mechanical properties in shock-loaded low carbon iron alloys is peak pressure. Pressure duration plays a role in the 13 to 33 GPa pressure range for duration, less than 1 mu/sec. Below 13 GPa and above 33 GPa the mechanical properties developed were not sensitive to the peak pressure durations used in the study. The alpha yields epsilon yields alpha phase transformation is playing such as major role in microstructure development above 13 GPa that any modification to structure associated with rarefaction rate is a second order contribution. This study validates previous work on shock loading of iron where rarefaction rate was not considered.
