... expression, T α , is extensively discussed. Then, emphasis is put on the stress-strain behavior in tension and compression over the low deformation range covering the elastic, anelastic, and viscoplastic response. The reported data depend, as expected, on temperature and strain rate and also, markedly...

... experimental results show that HSLA-100 steel has apparent strain rate sensitivity at rates exceeding 3000 s −1 and has minimal ability to store energy of cold work at high deformation rate. In addition, both strain based and energy based failure criteria are effective in describing the propensity of HSLA-100...

CB10TSS has the highest ductility with the highest elongation under tensile deformation; therefore the most energy is required to initiate cracks and to subsequently propagate them. In Charpy impact tests for unnotched specimens, the addition of rubbery particles does not improve...

It was found that formability LDH and failure location depended on weld location, and LDH increased when weld line was positioned at the extreme positions away from the center due to more uniform strain distribution on the deformed dome. The welded blanks had lower formability...
