Název v původním jazyce

Microstructure, mechanical and corrosion properties of extruded milled magnesium powder

Popis výsledku v původním jazyce

This paper deals with the preparation of pure Mg by extrusion of milled powder. The milling process should lead to better homogeneity of microstructure and the disturbing of the oxide layer on the powder particles. Also, the input deformation energy in the milled powder should affect the deformation and recrystallization process during extrusion. In this paper, the influence of extrusion temperature on microstructure, mechanical, and corrosion properties is evaluated. Higher extrusion temperature leads to the larger deformed grains in the extrusion direction and higher tensile strengths. On the other hand, the plasticity and compressive yield strengths are reduced with higher extrusion temperatures. Corrosion properties are negatively affected by the iron inclusions incorporated in the structure during milling. Otherwise, corrosion resistance decreases with increasing extrusion temperature due to the grain size.
