Abstract

The paper presents the basic properties of materials and technology of hot forging of Al-alloy parts. For alloys EN AW 2007 and EN AW 2024 the possibility of new technological procedure for casting Al-alloys under the influence of electromagnetic field was investigated. Such a procedure enables modification of microstructure and improvement of mechanical properties of ingots. In addition to that, the paper presents analysis of forging in manufacturing conditions for alloy obtained by extrusion with the application of suitable SC.SuperForge software for 3D problems. The obtained results show the equivalent stress distribution in work-piece which is being formed.
