The microstructure and mechanical properties of as-cast and extruded Mg-6Zn-1Mn-4Sn-xNd (x=0, 0.5, 1.0, 1.5) alloys were investigated by means of optical microscopy (OM), X-ray diffraction (XRD), scanning electron microscopy (SEM) and tensile test. The results showed that the dendrites sizes of these alloys were decreased by the addition of Nd. The phase compositions of the as-cast Mg-Zn-Mn-Sn-Nd...
The structural and spectroscopic properties of MgAl 2 O 4 :1%Nd 3+ spinel nanocrystals and ceramics were measured and analyzed. Ceramics were prepared from the above mentioned spinel nanocrystals and undoped commercial spinel powder, using the spark plasma sintering (SPS) method. Properties of the obtained ceramics strongly depended on the SPS conditions. The samples were not...
