Abstract: The Hugoniot elastic limit and spall strength of reactor steel 09G2SA-A under shock compression were measured by recording and subsequent analysis of the wave profiles. The temperature-rate dependences of the resistance to high-strain rate and fracture of steel at normal and elevated temperatures are determined. The results of measurements of the strength characteristics of steel under spall are supplemented by a metallographic analysis of the fracture zone and compared with data for 15Kh2NMFA reactor steel and Armco iron.

Keywords: ferrite-pearlite steel, shock waves, deformation, temperature, Hugoniot elastic limit, spall strength.
