An attempt has been made by the authors to construct the equation of the state for the tensile deformation in order to clarify the influence of strain-rate and temperature on the flow stress of mild steel.
In the present investigation an equation giving the relation among strain, strain-rate, temperature and dislocation density has been set up, taking both the strain-aging and recovery processes into consideration. The equation has been materialized in predicting the dislocation densities of low carbon steel deformed in tension under various test conditions(i.e.ε=0.1, 100%/min, temp.=R.T. 600°C). Validity of the equation was examined experimentally by X-ray profile analysis.
