Abstract

The article presents the tests results which tested the possibilities of shaping magnesium alloys. Testing materials were ingots from magnesium alloys with symbols LAE442 (Mg-Li 4%) and WE43. One of the aims of conduction of plastic shaping tests with the use of KOBO method was to achieve a product in the form of flat bars. The paper presents the results of mechanical tests of tested alloys marked in a uniaxial tension test in room temperature and in elevated temperature for achieved flat bars. Fractographic tests were conducted in tension test in order to determine the mechanism of cracking. A microstructure analysis was conducted both in the initial condition and in condition after plastic strain with the use of techniques of light microscopy and scanning microscopy.

Keywords: Magnesium alloys, microstructure, tensile test, fractography, hot deformation
