Paper Title:
Numerical Simulation and Experimental Investigation of High Strain Rate Superplastic Forming (SPF) of Al-6Mg-0.2Sc Alloy
  Abstract

FEM analysis has proved to be a powerful investigative tool capable of encompassing all the aspects that characterise an SPF process. In this paper, with the aid of a commercial finite element software is used to simulate high strain rate superplastic bulging process of Al-6Mg-0.2Sc alloy sheet box part under different technological parameters such as with and without lubrication. Base on obtaining optimum the loading curve, the strain rate distributions and thickness distribution in forming process by FE simulation, the relative validation experiments be carried out. It was found that the thickness gradient of the formed parts will be effectively improved reducing the interfacial friction by use of a lubrication at a higher strain rate forming. The results of the experiments are in good accordance with the FE numerical predictions both in terms of thickness distribution and forming times.
