The analysis of the effects of the chemical composition and the thermomechanical treatment on the characteristics of the extruded ALMgSi profiles

Abstract

In the paper are given the analysis results of the effect of the chemical composition and thermomechanical treatment on the mechanical properties of the extruded and aged AlMgSi profiles. On the basis of the obtained results and the performed analysis, it can be stated that a good combination of the characteristics of strength and plasticity of the cited alloys has been obtained as the result of the constructive designing of the chemical composition and the parameters of the thermomechanical treatment.
