Use of different flow stresses for forming inhomogeneously heated billets
Final Report Abstract
In the project "Utilization of different flow stresses in the forming of inhomogeneously heated billets", the effect of inhomogeneous inductive heating of billets on the subsequent steps of a forging process chain was investigated. For this purpose, both simulative and experimental tests were carried out to generate an inhomogeneous temperature profile by means of inductive heating. Here it was possible to generate inhomogeneous temperature profiles suitable for subsequent hot forging. Following the heating tests, simulative and experimental tests were carried out to analyze forging process chains with inhomogeneous and homogeneous temperature profiles. It was shown that the use of inhomogeneous billet heating is associated with material savings of up to 17.5% by volume. Metallographic analyses of the components showed that the inhomogeneous heating of the billet has no significant effect on the metallic structure of the blanks and thus on the mechanical properties of the components to be produced.
