Title: Simulation And Experimental Results Of The Hot Metal Gas Forming Technology For High Strength Steel And Stainless Steel Tubes Forming

Abstract

Simulation is a key topic within the development of the H lowbar ot M lowbar etal G lowbar as F lowbar orming (HMGF) technology. In this work, tube bulge tests and tubes forming processes using dies were simulated at high temperatures by means of FEM. The tube deformations calculated by the numerical simulations were compared to the results from experiments carried out at different heating conditions and using different input pressure curves. Flow curves for several stainless and high strength steels were experimentally determined in order to be used for the simulation code. Ferritic stainless steel 1.4512 showed very high formability capabilities at high temperatures. During tube bulge tests of the ferritic steel a maximum expansion of tube diameter up to 55% was reached by using a pressure of only 14 bars.
