Characterisation of structure, mechanical and corrosion properties of pure magnesium prepared by powder metallurgy route

Popis výsledku v původním jazyce

Powder metallurgy is a progressive method for materials production. Final products are usually characterised by improved strength and corrosion properties compared to materials prepared by conventional methods like casting and subsequent thermomechanical processing. The presented work studies the effect of extrusion temperature on the microstructure and properties of products prepared from pure Mg powder. It has been observed that higher extrusion temperature led to the formation of larger grains and massive oxides at interparticle boundaries. Tensile yield strength, compressive, and tensile ultimate strengths were increased at the cost of lower plasticity. The observed mechanical properties were mainly affected by texture, oxides, and grain size. The high corrosion rate was attributed to the presence of a relatively high amount of oxides and impurities which facilitate localized corrosion.
