Abstract:
In this study, we present the results of the recording of shock-wave phenomena in 15Kh2NMFA steel at room temperature and 504 $\pm$ 5$^{\circ}$C. Based on measurements of the free surface velocity histories, the dependences of the material resistance to deformation and fracture on the strain rate are determined. 15Kh2NMFA steel was found to be characterized by a twice higher dynamic tensile strength than iron, with almost equal values of the Hugoniot elastic limit. At increasing temperature, the Hugoniot elastic limit of steel decreases faster than that of iron while the dynamic tensile strength varies slightly.
