Abstract
This paper focuses on the heterogeneity of hardness distribution in the AA2014-T6 billets upset under rigid dies. The solid cylinders of height 24 mm and diameter 24 mm were compressed to different levels of strains by employing soap, boric acid and vaseline as lubricants on the faces of the billets and the friction factor (m) obtained from the ring compression test for the lubricants was given as input to the finite element software to examine strain distribution inside the cylinders. The strain distribution in the solid cylinders were correlated with the hardness distribution (VHN) and an equation was proposed to obtain the hardness of the billet. The Hill-Vonmises anisotropy factor was introduced to study the effect of anisotropy on the hardness of the deformed billet. The equation correlating the anisotropy and hardness was utilized to study the effect of anisotropy and the material parameter (C1) on the hardness of the billet.
