In the present work Mn3O4 nanoparticles (NPs) with spinel structure were synthesized successfully via combustion route with MnIII(acac)3 as precursor in two different temperatures. The morphology of the synthesized Mn3O4 were investigated by field emission scanning electron microscope (FESEM) and structural analysis was studied by po...

This paper presents how the mechanical properties, microstructure and degradation rate of extruded Mn-containing Mg-Gd alloys can be modified during extrusion. Gd as a rare earth element is particularly interesting due to influence on texture development in Mg, therefore studied base alloy system. The contents were investigated between 2 9 wt.%, with Mn additions 0.5 1.0 wt.%. grain sizes corre...

Aluminium and its alloys belong to the most widely used metallic materials for industrial applications. One of the possible casting methods is twin-roll casting which produces sheets with high solid solution supersaturation. Decomposition of this supersaturated material during heat treatment was studied in aluminium alloys from the AW-3003 series – one standard grade and the other modified by a...
