Mechanical and microstructural properties of Mg-based AZ31 alloy processed by ARB

Popis výsledku v původním jazyce

Severe plastic deformation techniques are known to produce materials with ultrafine-grained structures and enhanced mechanical properties. In magnesium alloys, these techniques improve both strength and ductility, as the latter is normally low at room temperature. In the present experiment, properties of rolled products after two rolling passes were examined. Rolling was carried out at 350°C and 400°C. At 350°C, the rolled sheets did not bond. Mechanical properties of the rolled products were determined. Microhardness profiles were measured to map the deformation distribution. The impact of the number of passes on mechanical properties was evaluated. It was found that with increasing number of passes, ultimate strength yield strength improve, and elongation does not decrease. Metallographic examination of the rolled products was carried out to assess the quality of the resulting joint. In certain locations, the joint was not distinctly visible, which proves its high quality.
