Isothermal Forging of Ti-6Al-4V Alloy - Flow Stress Evaluation and Optimization

Authors(3) :-Azhar Equbal, Md. Israr Equbal, R.K Ohdar

Narrow-forging-temperature range makes titanium alloys tough to forge. In this paper hot compression experiments on Ti-6Al-4V alloy specimens are conducted using Thermo mechanical Simulator Gleeble-3500. These objectives of the test were to obtain flow stress data under varying conditions of strain, strain rate and temperature. Furthermore, artificial neural network (ANN) was used for studying high temperature flow characteristics for Ti-6Al-4V alloy in terms of stress–strain curves. A predicting model was also established for the calculation of flow stress using ANN. Results show that the neural network can correctly reproduce the flow stress in the sampled data and can also predict the non-sampled data very well. These studies are significant for determining the hot-forging processing parameters of Ti-6Al-4V alloy.
