Abstract

Tensile flow curves of interstitial-free (IF) and C- and Padded (CP) steels were measured at temperatures from 77 to 773 K with a strain rate of 3.3 × 10−3 s−1. Flow curves at 2.0 × 10−3 s−1 were estimated by using the Kocks-Mecking model and compared with the results obtained by a Hopkinson pressure bar method. Flow stresses at 2.0 × 103 s−1 were satisfactorily estimated when the parameters of the model were determined from the data obtained at low strain rates both for IF and CP steels. The temperature dependence of the deformation microstructure evolution hardly affected the flow stress when a temperature change test was performed. The flow stress ratio or difference between 2.0 × 103 s−1 and 3.3×10−3 s−1 at 295 K was larger for IF steel than for CP steel although a thermal component of flow stress at 0 K was estimated to increase by solid solution hardening. These results are reasonably explained by a model calculation.
