From hot forging to thixoforging: FEM analysis of thixoforging process for steering piston production

In this paper evolution from hot forging to thixoforging process is proposed and talked over. A realcase study is presented, namely a steel-made steering piston produced by thixoforging technique is considered and some parameter has been numerically analyzed. The transition between the traditional forging process and the new one involves several transformations and presents difficulties mainly due to the high working temperature. The targeted thixoforging technology allows obtaining near-net-shape components with a significant reduction as the starting material quantity concerns, and implicitly of the involved amount of energy.
