Shear and Spall Strength of Quenched 30KhGSA Steel during Shock-Wave Loading in the Solid-Phase Transformation Region

摘要

The optical lever method is used to obtain new data characterizing the dynamic properties of quenched 30KhGSA steel in the loading range up to 30 GPa. These data include the shock compressibility(below and above σ_(χχ)~(α-ε) =15 GPa, which corresponds to the α'-ε transformation in the steel), the shearand spall strength, and the kinetic laws of the interrelated processes of high-rate deformation and fracture. These systematic experimental data are of interest and can be used to verify modern interrelated kinetic multilevel strength models for the steel under study and to certify two-dimensional software packages.
