The contemporary challenge in automotive industry is weight reduction for better fuel economy and low greenhouse gases. Compared to conventional automotive materials, aluminium alloy has enhanced strength-to-mass ratio and low density, which confers to optimal requirement for automotive applications. Besides casting, Aluminium alloy forging is emerging as a new area, where deep research is required for evaluation of the forgeability with respect to forging parameters such as forging equipment, heating temperature, deformation temperature and post forging treatments. In this paper Al 6061 T6 alloy was thus selected and forgeability is evaluated for various manufacturing conditions. To understand the material behavior the forging process is physically simulated by thermo mechanical experiments. The experiments were carried out using Gleeble simulator at three different temperature (350°C, 400°C & 450°C) and at three different strain rates (0.2s-1, 2 s-1, 20 s-1). The three strain rate is selected to represent the forging equipment which works on force, stroke and energy dependent principles. Material characterization activity was carried out for the sample and the entire experiments were simulated using FORGE software to correlate the results. The forgeability of the material is observed good at all the strain rates for 2/3rdreduction ratio and significant difference is observed in the mechanical behavior for three different temperatures. © 2015 Elsevier Ltd.
