Conclusions
-
1.
In static tensile tests of samples strengthened by preliminary strain the yield strength is low when the preliminary strain rate is high.
-
2.
The static strength of samples subjected to preliminary strain at different rates varies with the carbon content of the steel. Carbon steels with <0.22% C have a low static strength and steels with >0.22%C a high static strength, depending on the preliminary strain rate.
-
3.
The larger the preliminary strain, the larger the effect of the preliminary strain rate on the static strength characteristics (σT, σb).
