Abstract
To understand the flow stress behavior of a grain size gradient structure, generalized stress and strain relationships in both torsion and tension are analyzed in terms of continuum mechanics. The results show that the twisting moment in torsion and flow strength in tension increase when the grain size decreases as a function of the radial distance in a cylindrical specimen. For experimental comparison, a grain size gradient is produced, through a thermomechanical process of torsioning and annealing, in a mild carbon steel of AISI 1018. The effect of the gradient structure is then tested for both torsional and tensile properties of the steel.
