Biaxial Gas-Pressure Forming of a Duplex Stainless Steel

摘要：

By using biaxial gas-pressure forming method, it is possible to predict sheet metal forming behavior during hot forming process. The purpose of this study is to investigate the deformation behavior during equi-biaxial forming of a duplex stainless steel using conical and hemispherical dies. The present study constructs an analysis model to predict biaxial sheet forming behavior of duplex steel from results of tension tests. The results demonstrate that the developed technology to process design of high temperature gas-pressure forming by the finite element method can be applied to various types of components.
