Abstract

The paper presents analysis of plasticity characteristics and microstructure of magnesium alloy type WE43 with yttrium, zirconium and rare earth elements. Susceptibility of magnesium alloy to cracking in high temperatures was tested on Gleeble3800 simulator. Zero resistance temperature and zero plasticity were determined. Tests were conducted for assessment of susceptibility of tested alloys to hot plastic deformation. A tensile test was performed in temperature range from 250 to 450°C. On the basis of the results, ultimate tensile strength and reduction of area were determined for tested samples. A varied plasticity of tested alloys was found depending on aluminium content. Tests results will be useful in development of forging technology for chosen construction elements which serve as light substitutes of currently used materials.

Keywords: magnesium alloy, tests of plasticity, microstructure, mechanical properties, cracking
