Abstract
Magnesium is the lightest metal used for construction elements. Due to their lightness and good mechanical properties, magnesium alloys have been used in aviation industry since 50's of the last century. Magnesium - Lithium alloys are the lightest of all magnesium alloys. Their density can be lower than 1.0 g/cm3. In this paper the results of numerical simulation of direct extrusion of Mg-Li alloy hollow profile are presented. The alloy contains 12 wt.% addition of Lithium and was extruded through porthole dies. The analysis of temperature distribution, metal flow, stress and strain was performed in Deform 3D software using Finite Element Method (FEM). The mathematical simulations were performed for various temperatures of ingots and various geometries of a die. Thanks to numerical simulations, the optimal temperature and geometry of a die were determined and consequently optimal stress conditions in a welding chamber were obtained. © (2015) Trans Tech Publications, Switzerland.
