... mechanical constitutive behavior of high strength low alloy steel HSLA-100 is experimentally characterized over a wide range of strain rates, ranging from 10 −3 s −1 to 10 4 s −1 . The ability of HSLA-100 steel to store energy of cold work in adiabatic conditions is assessed through the direct measurement...

...M. E. Kassner; P. Geantil; R. S. Rosen This study reports the significant ambient temperature creep plasticity at stresses below the conventional 0.2% plastic strain off-set yield stress. This is partially due to the relatively high strain-rate sensitivity of 304 stainless steel. Cold-working...

..., this study examines using an electrical current to reduce the deformation energy and presents electricity’s effects on the tensile properties of various materials. The influences of strain rate and cold work are also investigated. The results demonstrate that, when current flows through a metallic specimen...
