Uniform Ductility of High Carbon Steels

Abstract

<p>The effect of microstructure on uniform ductility was analyzed by utilizing a fact that uniform ductility is equal to the work hardening coefficient in parabolic true stress-true strain equation. A Hall-Petch relation was found for the flow stress of lamellar and spheroidized high carbon steels. The uniform ductility was formulated as a function of reciprocal flow stress and found to fit the experimental data.</p. <p>An attempt to interpret the results obtained, based on the scanning and transmission electron microscopy observations, were given.</p>
