Abstract
Simulation is a key topic within the development of the Hot Metal Gas Forming (HMGF) technology. In this work, tuve bulge tests and tubes forming processes using diez were simulated at high temperaturas by means of FEM. The tuve deformations is calculated by thenumerical 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 simualtion code. Ferritic stainless steel 1.4512 showed very high formability capabiliites at high temperatures. During tube bulge tests of the ferritic Steel a máximum expansión of tuve diameter up to 55% was recahed by using a pressure of only 14 bars.
