บทคัดย่อ

The influence of strain rate on the mechanical properties of microalloyed steels for cold drawing grades S 315 MC and S 460 MC was investigated. It has been shown that strain rates in the range from 10-3  to 1 s-1 did not significantly influence the mechanical properties. Significant strengthening was provided at strain rates exceeding 2 s-1. It has been also shown that the basic mechanical properties of the cold worked tested steels in the extent from 5 to 25 % were not influenced by pre-strain with strain rates from 10-3 to 103 s-1. It is supposed according to the results, that the susceptibility to cold work of these steels was not influenced greaty by the strain rates usually used for cold work (less than 1 s-1) and that the products after cold work maintain their mechanical properties.
